high rev?
I installed an egr delete on my 04 6.0 this weekend with an oil cooler, screen, hpop gaskets, intake gaskets and oil change. Then when i drove it down the road it would rev up and shift hard. I checked the trans fluid it is good and went back over my work and every thing is hooked up. I did notice that my fuel filter cap on top of the motor was leaking and i bought one from ford this morning and put it on. My question is would the cap allow air into the system and cause my problem or could it be something else? Thanks

No the cap would have nothing to do with it. Did you by chance unhook the batteries? It could just be going through a trans re-learn process now.
|
Yes the batteries were unhooked. I started it at 5 on friday and they stayed unhooked till 12 noon on sat. What will I need to do to get it rite again? Thanks for your help!
|
Sounds like it could be that. You don't have to do anything other than drive it... it will teach itself how to shift again.
|
Thanks. I drove it about 60 miles this morning and it is still doing the same thing. Just don't want to mess anything else up. Maybe that's what it is. Thanks again.
|
If it continues to do it without getting any better, it may be something else. Usually a long battery disconnect like you said will do this though. There is an actual trans re-learn process you can do to speed it up though. I will try and find it.

Thanks mdub that would be great

I can't find anything in writing, but from what I remember. Go out some place where you can start/stop and run through all the gears.
From a dead stop, lightly accelerate through all of the gears. Essentially you're just going to keep repeating this process gradually getting harder and harder on the throttle every time. I believe bullydog recommends this when changing their tunes on their programmers since they do nothing for the trans as far as tuning. It's not really complicated, and realisitcally it will figure itself out. I think this just speeds it up. |
Ok so I did the trans re-learn process and the vgt re-learn process and drove it again. This time the check eng light came on. Took it to the parts store and the code was icp sensor. A local shop said that was normal with the way it was acting and they seem to think that its still in the re-learn process, to keep driving it and see how it does. What do yall think?

How is the motor running? Any issues with it? If you have an early 04 that ICP is more of a PITA to change as it's on the back of the motor below the turbo. If it's a late 04 it will be on the passenger side valve cover.
Did you find a place that described the trans and VGT re-learn? Post it up if you did. I'd hate to see you get stranded somewhere cause of the sensor though. When they start getting real bad sometimes the truck will have issues re-starting when shut off. |
Mine is the later 04. The icp is on the p/s valve cover. I'm taking it to a shop friday if it doesn't get any better. I will find the link to the trans and vgt re-learn and try to post it up tomorrow if I can figure out how to. Thanks again. The truck runs great if you get on it hard. But idles rough. If you hold the brake when stopped it smooths out and still shifts hard/slips? When easing on the gas but shifts good when on the gas hard.
