and now SCT is saying that it looks like the PCM/TCM could be taken a crap......i just checked the codes again and no lost com. codes but the P2263 and P006B are there now, havent seen the P006B yet i dont think.............................

oh ya thats the MAP/EBP corelation code.....my bad, ill try to unplug the EGR right now

 

Assuming the EGR is closed when you unplug it, it should remain that way.

 

it must be sticking...i dont know, i removed the black plastic cover of the EGR valve, the plunger inside is spring loaded....and was easily pressed down and would pop right back up......i dont know but unpluging it didnt help

 

I'm thinking since you took that valve apart, she's probly no good now.

I think you need to find a mod friendly dealer - so they can look at this with the tunes on it to see if it's a ford issue or a tuner issue.

Does the truck work ok with all the stock junk on it?

 

ok, i have a philosophy.....because i had a tuner and a module stacked running the DPF/DOC probably plugged one up, if not both....ok, and the EGR is probably got some sh-t in it too, considering.....so if the EGR is full of crap too then would it cause it to stick, or just trip-out once and awhile???? i dont know, and i have never had this type of problem before......its just crazy that it will run great tuned with DPF/DOC,and EGR delete options, no DPF/DOC components, for an unsertain amount of time(everytime), and then be shut down(count to 20-30), started again, and run great once agian like nothing happened...only to repeat itself and do the same sh-t all over again, and agian....

wait, do you mean completely stock exhaust and all, or dpf/doc and tune stock????

---AutoMerged DoublePost---

and maybe im looking at the wrong valve, because this thing came apart easily with three torx bolts and slid rite off and back on with not a hitch....do think i f-cked it up???

 

she goes in to the dealer on the morning.....got it all back to stock except the filter-back exhaust, cause it hasent arived yet.....sure hope they figure it out!?!

 

well after all that crap you guys will never guess what it was...................it turned out to be the EBP sensor. now is that some crazy sh-t or what?? i spent an excesive amount of cash tryin to trouble shoot and fix this thing, and in the end it turned out ot be a little sensor......WOW.............a word to the wise here, keep your factory componenets and when the thing starts to act funny and throw all kinds of funny codes put it back to stock and take it in.....they have alot better diagnostic equiptment then our tuners and modules and the techs are trained to diagnose problems like this and work on these types of trucks every day. Anyway my baby is back on the dusty path, WOO HOO

 

Something that everyone should keep in mind. Quoted for truth.

Fwiw, I've only changed ONE ebp sensor on a 6.4 so far, an this one was melted.

 

i didnt see the sensor, but the tech said that it definitly was malfunctioning.....i should have it back tomorro, i will tune her back up and post my findingsthe thing had to go right back in the next day because of a coolant leak....that turned out to be a hose from the cooling systm to the EGR cooler.

 

i finally got it back for good............drove it for a bit today stock just to check it out, then went home and tore her down......got her deleted, and tuned and boy she runs great............THANKYOU FOMOCO TECHS!!!!!!!! AND RIVER CITY DIESEL!!!!!!!
