I just bought this truck the 24th and I think it may have a bad APPS. Here are the symptoms.
When I first get on the road in the morning while the truck is cold, the rpms will fluctuate slightly while I accelerate. Also, every so often, while I'm driving I'll let out of the throttle from a cruise and go to get back in it and have nothing(its like the truck is stuck at idle). I can pump the accelerator pedal several times and its like I make contact and the truck takes off as usual.
BTW, the truck is a 2001 4x4 Quad Cab 2500 4x4 Auto that is bone stock with 230,000 miles on it. It looks as if the injector pump and lift pump were replaced not too long ago as they are much cleaner than the rest of the engine.
I really hope this is as simple as the APPS. The CEL is not on, but I will be taking it to my buddies shop to scan for codes.
