I just started having this problem with my '04 the last couple weeks. Before the engine temp gauge moves, I have virtually no power. I can have my foot to the floor and the truck barely moves. It takes about 20-30 seconds to get enough RPM's for the turbo to kick in. It runs great as soon as it warms up, it is not running rough when cold, just won't hardly move. Even this afternoon, it was upper 50's out, I let it run for at least a minute before taking off, and this happened.
Mine also, I have to start in low when its cold. I had it in for service and it through NO codes. The tech was thinking tranny? I havent had time to get it back in, but they plan on pulling the tranny appart when I get it there. [img]/ubbthreads/images/graemlins/shrug.gif[/img]
Mines in right now, they started talking about thermostat or temp gauge. I told them it warms up fine, no variations in temp when it does warm up. I don't think it is the tranny either, both snap ring and planetary pins have been replaced. It just sounds like there isn't any fuel getting to it or something.
They supposedly had 1 other in just yesterday for the same thing.
GPJ, I could possibly accept this if it happened from the beginning. But neither of these 2 trucks that are exhibiting this problem have done it from the beginning. [img]/ubbthreads/images/graemlins/shrug.gif[/img]
It's not the tranny cause my 6 speed does the same thing! It needs to be warmed up before you mash the throttle. My 7.3 was the same way, I could not just get in the truck start it up and take off like a gasser!
My truck used to do the same thing. I mentioned it to the dealer and the found a bulleting for "dead pedal" or something like that. Anyway, they adjusted some calibrations on the PCM and I have not experienced the issue for the last 4K miles.
