I have a 95 that seems to rev slow. It has some glow plug issues I need to correct, but I dont think that has anything do do with it reving slowly. I thought it ran fine up till my brother in-law just bought a 96 with a PSD. He let me test drive it and sitting still and just hitting the throttle his truck reved way faster than mine. I mean his would rev to 3k like nothing. While mine seems to take forever compared to his. Driving down the road they seem about the same. His has an auto and mine has a 5 speed. I actually think mine gets up and goes better than his does even with an exhaust leak before the turbo. So what do you guys think. Would o rings on the injectors cause this? I think the are worn. I think I remember reading somewhere that if your motor runs rough from 2300-2900 when you just floor it that the o rings are shot? Is that true? My truck has 180k his has 140k. Thanks for any help.
they could be leaking, usually you get a little smoke from the tailpipe along with the rough accel. definatly need to fix the leaking up-pipes. does it still have a cat on it?
