Hey guys I'm new to the site. Need a little help. First 6.0 I've had and starts up fine but will barely move until warmed up??? It's throwing 2 codes (p0403 &p0405) after warmed up to temp it runs like a champ and all temps are fine... Anyone got some info for me please???

 

whats the status of your EGR??? (delete, stock, ect.)

those are both EGR codes

 

I just bought the truck yesterday... Not sure how to tell if it has a delete...Has edge evolution programmer

I just bought the truck yesterday... Not sure how to tell if it has a delete...Has edge evolution programmer, cold air intake and cat back exhaust... That's all I know about it.

 

Welcome to the site!

Let's start here:

I understand you probably don't know the full history, but any info you can give will help us. Your two codes are both EGR function codes.

 

Ok well I took a look and it has a sinister cap were the egr was... So I'm guessing it has a delete kit... 2004 f350srw 6.0l 147,000 miles sinister delete kit edge evolution programmer cold air intake.
Eot 185-190 ect 185-192

lacks power
my 2006 psd when its not warmed up stumbles and acts like its missing. lacks power too. when the engine warns up this all goes away. ive had it to 2 ford dealers and both have told me nothing is wrong with it....it doesnt matter if its cold or warm out either

This is exactly what my truck is doing... Except I have a 2004.
So I'm going to buy some rev-x and see if that fixes it.
And I was thinking its only throwing the egr codes bc of the delete and since there is no egr...
Hope it works

how can i tell if it has a oil cooler delete? and the kam code came up on my edge???

---AutoMerged DoublePost---

when it starts it blows white smoke and it smells like oil and fuel, not the sweet smell of coolant.

 

Sticky injectors likely... I would test the FICM.

Rev-x is not a fix for anything. Does it work? Yes, it works very well, but it's essentially a "cover up" for a problem.

Your EGR codes are likely just soft codes due to the delete, not an issue.

 

thanks alot ill try to do it tomorrow!!! the sticky injectors wouldnt throw a code? does my edge evolution read all the codes on the truck or do i have to have the dealer scan it?

 

Typically no you wont get a code for an injector unless it's a hard fail. Sticky one's typically don't show crap. A dealer's scanner (they use IDS), or even autoenginuity could POSSIBLY pick it up in a cylinder contribution test, but even then it's difficult because they will usually clear up as the truck warms up.

the Edge will read basic codes, but can't really "scan" like a diagnostic's tool. I typically recommend AutoEnginuity with the enhanced Ford bundle for our trucks for the DIY guy. It's ~$350, but you will need a labtop to run it.

 

Ok still doing the roughy start... I tested the ficm today and I got 47.5-48 koeo, and 48 for the other 2... So ficm is good... So it would be bad injector/injectors or bad glow plug/plugs??? Did all the maintenance since I didn't know what was done when I bought it. When I get the rev-x and put it in and it straightens out will that tell me injectors? Any suggestions??? Thanks again guys for your help and more to come!!!!

And I also want to tear the turbo apart and clean it since I don't know how long it sat at the dealer... What gaskets do I need if any are needed?

 

you can get a turbo hardware kit that has the oil supply line gasket which the the only gasket that you need, while you are there get the updated oil drain tube and oil supply line, it helps lube the turbo better
