snowlvr 6.4L wont go
 

was looking for an answer on my 6.4L ford....it acts as though the dpf or doc is clogged.... runs decent however restricted when first started warm or cold, then a few minutes of normal driving brings on a surious amount of mhat seems to be lag....and will only produce about 70% of hp.....if i ignore the problem and keep driving it seems to go into a backdown mode or something and wont accellerate at all, if i lay on the go pedal it will slowly build enough boost to take off...and i mean slowly. if it sounds like the dpf like i thought, i will delete it....any suggestions???

Is it fully stock or does it have any mods??

the truck has afe stage 2, mbrp exhaust, and edge juice w/attitude stacked w/a superchips cortex......6in lift on 37s

Remove the boxes and see if it helps. Chances are you lost an injector and it melted the DPF.

it has thrown several codes, one is a turbo performance code , the others are dpf and egr codes which lead me to believe that it is the dpf or doc causing the problems....computer reading to much backpressure and shutting it all down.....also will throw MAP/EBP corelation code from time to time:argh:

---AutoMerged DoublePost---

i have had the boxes off with no change in performance...:argh:

---AutoMerged DoublePost---

has also had out of ordinary EGTs....does that help??

---AutoMerged DoublePost---

once had an injector curcuit code and took it to ford..... they siad it was the juice that caused it...i sent it back to EGDE and they sent me a new unit.....havent had any problems w anything for a while outside of ford replacing the radiator and normal recall B>S>

How does the engine run?? I mean any excessive amounts of white smoke, rough idle, lot of ticking??

if it lost and injector would it throw a code for that?? the dpf is an easy fix, the injector idea however is not........

---AutoMerged DoublePost---

no....the thing semms to run fine till you step on the go pedal

---AutoMerged DoublePost---

no funny noises at all and runs smooth, just seems to not want to go...like it has a Fing apple in the tailpipe:humm:

As far as I know, it won't throw a code if an injector went out.

no smoke at all

I suppose you tried driving down the road to try and unclog the DPF.

wouldnt the truck shutter and run rough with a lost injector.....it dosent seem like that is it, i mean im new to diesels but when its time for that specific injector to do its job there would be a blank.....cuasing a shutter or cut-out so to speak...right??

---AutoMerged DoublePost---

i drove the thing 230 miles running like this last wknd in an atempt to do that very thing with no avail.....somthing else that caught my attention is that on a trip like that the truck normally would regerate about 3 times...when it only did one time on the way home....:argh:

---AutoMerged DoublePost---

have been putting off the dpf delete and tunes from spartan....what do you think i should do bout this little delema?????????:humm:

might be time to have a dealer take a look. take off all the aftermarket boxes and carry it in.

tried that..and without stock everything they wont even read the codes and i dont have the stock intake or exuast....so thats why im asking here, and not there

---AutoMerged DoublePost---

the factory exuast had to be cut to get it off, and the air intake was disposed of properly by throwing it in the dumpster at my house

Could also be bad turbos, or the DPF is throwing it into limp mode.

hope its not the turbo(s) OUCH!! but limp mode makes sence, becuase when it does spool boy does it spool, sounds fine etc. just really acts like its got a apple in its mouth and a ---- in its booty..

---AutoMerged DoublePost---

aslo when the truck did regen, it seems to run pretty good, i mean for a regen...no lag at all and plenty of poop, just no top end ....total opposite of how its been running normal:argh:

well, still no change in condition...i have noticed however if i baby the truck it runs pretty good (except for the terrible lag).... when i decide to push it alittle is when the egr trouble code will throw, and the problems start............maybe this bit of info will help

---AutoMerged DoublePost---

i still think it is the DPF... i was counting on it plugging premature becuase of the stacked tuner and module on the truck for such a prolonged period of time.....anyhoo its not fixin itself and im still waiting on funds for the delete... i did check w/fomoco about stock dpf-back piping and air intake, itll be about a grand for both..as a last resort that may be an option to just return the truck to OEM and bring it in for the FORD guys to figure out

---AutoMerged DoublePost---

:argh::argh::argh:

---AutoMerged DoublePost---

what might happen if i remove the dpf before i get the kit??

---AutoMerged DoublePost---

will the truck regen constantly or the same....maybe not at all......and does anyone think im wrong in assuming the dpf would clog prematurely because of the stacked tuner and module on the truck????

6.4L no-power blues
 

08 6.4L with 26000 miles, starts fine and runs good till warms up then will still run fine if i baby the thing, however if i try to take off fast the thing wants to lag up REAL bad...then will through the egr code, map/ebp corelation, turbo performance codes....after this the simptoms get worse and worse untill the truck runs smoothly but will not accell.....i mean i can stand on the thing and it wont even bark............please help


the truck since bought new in january of 08 ahs had afe stage 2,mbrp filter back pipes,and edge juice/attitude stacked w/a superchips cortex:humm:

still no go
 

its to the point now that im not driving the thing at all....ive heard several cuases for my issue and the only two that make sence are the plugged dpf, and the BUY-BACK issue that NO one seems to know what caused it.....hoping someone can help,

again the truck is a 6.4L f-250, afe stage 2, mbrp filter-back pipe, and edge juice w/attitude stacked ontop of a superchips cortex....6in fabtech lift, 37in rubber, and lots of electronics:argh::argh::argh:

---AutoMerged DoublePost---

i have noticed that the exsuast seems to be baffled, both in sound and flow...i mean it used to blow ur hat off and singe your eyebrows if u got to close...now it barely blows ur hair back:humm:

---AutoMerged DoublePost---

im affraid that if i drive it like this it will only make things worse.............someone please, some info

try taking all the performance boxes/programmers off an let the truck regen on its own. see if that helps.

And I wouldn't be stacking 2 boxes that add Timing. Your just asking for troubles.

the staked boxes have been on the truck since the truck was delivered to me....i have never had a problem till now, i have been looking at a dpf/doc delete and egr block plate, the new tunes will come from spartan or elite diesel.....the problem is that i dont know if the money im about to drop on the delete and tunes are guna fix my problem....or, should i spend the coin on returning the truck to stock ( aprox. $1000) and take it in??:humm::humm:

---AutoMerged DoublePost---

also to respond to the regen q....i have driven the truck about 230 miles with both tuners on the truck, but had the edge turned all the way down.... i definelty could try the suggestion, all though i have driven the truck quite a bit around town with the cortex removed and the edge turned to 0 (stock).......so u want me to take the edge module completely off the truck, then drive till it regens????

yes. take all electronics that may interfere with the regen process off the truck and let the factory computer take over completely for a while and see if it will regen and clean the DPF out...

It sounds like it's going into limp mode ??? Is your DPF clogged with soot ????

did it...only drove 20 miles but no regen, no codes either....but still lots of lag and only 25-30 psi of boost......consistant though, only thing..when i started the truck and let it warm up for a few minutes it had hardly no exhaust, and when i returned home it was blowin alot better...and HOT, that is what leads me to believe it is the DPF, the EGTs are hella high and it really runs like bubba has his size 13 in the tail pipe......just feels like there is a surious restriction some where.....i thought at first it was a egr problem but sources say the egr will not affect performance even if stuck ON, well how the F could that be true if the purpose of the egr os to put fresh off the manifold hot gases badk onto the intake charge....just saying that i know its b.s. becuase it wld be like eatin a big breakfast and going for a jog...well half way breakfast makes a run for it and your lookin for a place to squat...well if you ate that crap would you run faster?? N O !! hell u probably if the choice was yours wouldnt even consider eatin your sh-t ..know what i'm gettin at? nothin im hearing makes any sence!:argh::argh:

---AutoMerged DoublePost---

im not finding a solution... like the little yellow guy is....beating my head ag:argh:ainst the wall

IIRC it takes more than a 20 mile cruise for a full regen to take place. if it were me i would drive it 50-100 miles highway driving.... that should get it to regen and clean anything in there out.

You'll need to monitor some data to determine the root cause.

If you can monitor EBP, watch what it's doing when you rug the loud pedal. Put the truck on the limiter (3700rpm) and see what the EBP is doing.

List all the codes and we'll see what I can do to help ya out.

Where do you live? Do you have a modification friendly technician you're working with?

sounds to me like the DPF is the problem....thanks for the straight forward answer..just on emore question though, how is it that every response ive got on this forum arre from guys drivin Cummins?? come on fomoco fans...time to step up.. and logically how would a guy in a dodge world surrounded by cummins, be able to answer questions and conserns about a pwerplant as new as the 6.4L???? i point is that i feel like the help i receive here isent help at all!

---AutoMerged DoublePost---

my engine in my ford is Not the sme thing as a cummins..nor does it act like a cummins when problems arrise...i understnd that they are all diesels but advice from dogde lovers is comenly enough (seell the ford for a dodge attitude) . i use this truck for my business and time is money..........thanx for the RUNAROUND!

come on ford guys throw me a bone here

I work for a company that has a ford and a dodge for deliveries and my personal truck is a ranger with a mazda diesel. I have to keep all of them on the road working. A lot of the guys that post help suggestions here are professionals that work on fords as well as dodge and gm daily. Their choice of personal vehicle has no bearing on their knowledge of other makes. To think that since they drive a dodge means they know nothing about a ford seems a little narrow minded to me. The advice is given with sometimes limited information, and I for one have very bad long distance x-ray vision. The advice is meant to help give ideas to search for a solution, not as an absolute this is what is bad.

People here are just trying to HELP you for FREE.

If you dont like it - you know where the door is. PLEASE feel free to use it.



Unbelievable!

nice....thanks for the help

if you dont like the advise than dont ask for it not all vehicles do the samething and it is hard sometimes to get a good feel for the problem by limited info given on your end but dfp regen

unbolt the dpf from the exhaust and leave a gap and take it for a run and see how it performs.... if she runs like a raped ape i think you knwo where the problem is... but then again what do i know....

SORRY fellas!! didnt mean to get under the skin...thanxs for the help

For one I take this completely personal. I have had many trucks, have worked on many diesels and every day try to better myself in knowledge on any diesel I can read and learn about, from 4bt's to Duramax's to Detroits, to Internationals to Perkins to the old Cummins in my old ass Dodge ram sittin' in my driveway that is paid for.

I try to help ANYONE that needs helps and actively seeks it. I'm not a brand "racist" I like all diesel owners, I miss my old Powerstroke every day but I'm not going to run out and buy a new one just so I can "prove" that an answer to a question is valid on my part. I have a family to take care of and can't afford a new truck payment.

So that being said I am sorry if because of my choice of vehicle my answers weren't valid enough for your narrow mind to accept them as the help you were asking for, then try them, and hope that it fixed your problems so the dealer wouldn't void all your warranty because you had 2 aftermarket programmers on the truck.

I am sorry you know more than me about your truck. Go fix it yourself and tell us what YOU did to fix it since we don't know anything and keep giving YOU the run around...... BTW the regen that i keep talking about in my 3 other post is the regeneration process where the DPF gets cleaned when it is clogged up. it sounds like it is clogged up from too much fuel (soot from too aggressive fueling) from 2 programmers.....

jeeze...guess the apology wasent accepted....none the less, i did say i was sorrry for the comment, and didnt mean to step on a nerve! SORRY AGAIN

No worries - we have thick skin BUT

Im sorry, but when you a new member of a site - its probably a good idea to treat people with courtousy and respect - at least until you know them or are a regular member of the site.

You are a new member here and have been treated with nothing but respect here. It is well beyond our control that your Ford brothers have not taken it upon themselves to chime in and help you out. In good faith, a number of people have tried to help you and your response was not acceptable. What specifically are we supposed to do to make sue you get an "acceptable" answer to your questions? Exactly, what else could we have done to help you out?

We cater to ALL BRANDS of DIESEL.

still benjamin, the comments that i have apologized for twice now, were not aimed specifically at you. or the cummins comunity, it wasent ment to strike a nerve either..i only ment ( obviously worded wrong) that i didnt feel as though the advice given made sence...you know could be this...or maybe, this....my bad! didnt mean AT ALL to make you feel obligated to a response either. once agian and for the last time i am sorry for any toes stepped on or house floors crapped on!!!!!!!!!!!!!!!!!!!!!

Its forgotten.

Now lets try to get you some help.

I dont know anything about Fords or much about EGR for that matter but it seems to me that with 2 fuel boxes you may be running too much fuel and the DPF is having trouble dealing with it. Does that not seem sensible?

---AutoMerged DoublePost---

that is a very sensible answer ....thankyou very much, and have a great evening
