studdering

MacDougall · #1 (**permalink**) 12-19-2009, 08:24 AM

Okay, so when i first start my truck and untill it gets up to temp it will studder a little bit, and when i accelerate lightly it does it. it seems like it is going to die but doesnt. it just chugs until it is up to temp then it seems to stop, if i let it sit for an hour it will start doing it again until it is running at normal temp. any ideas? oh and no CEL, and its an 2002 F350.

Sounds like the ebpv is sticking on you.

+1 for the ebpv.... unplug it at the turbo, see if it does it

Ill unplug it and see but i really dont think that is it. it seems more like the ICP sensor to me but not sure if that would do this. oh and i have a dp-tuner, with it on the 140 setting it seems to have alot of power, but when i put it back to stock it has NO power, way less power then stock should have. i dont know if what ever is wrong has to do with this or not or if i have 2 problems.

If not the ebpv, could be the ipr valve. IIRC, mine done pretty much the same thing. I had to put the 6 pos chip over to extreme setting to get my truck to move. mmmm
