jumpy acceleration

deadred · May 31, 2007

Im kind of confused as to whats goin on with my car...when i accelerate its jumpy it doesnt fully accelerate

its kinda hard to explain..i changed all four cylinders coil packs as well as the plugs thinking it was misfiring but to no avail its still doing it...is this a rev limiter? does anyone know? does anyone have the same problem?
thanks in advance http://****************.com/smile/emthup.gif

What have you done to the car? If it's chipped you most likely need to swap out the n75 or whatever valve.

When I chipped my car (giac x+) the power band was very unsteady

check the coilpack harness, it's a common problem.

what does the n75 valve do?

There are a few different valves, some give slightly more boost than others while some give smoother acceleration. I'd bet that will help your problem. Is the jumpy acceleration under wot or partial thortel?

Re: (lookin4avw)

umm. it usually happens partial throttle and in low gears

thats how mine is with the same programming. Honestly I'd just learn to deal with it, it is a pain but you can get used to it. Besides its more important to have smooth acceleration when its wide open right?

I have the same thing. I get on it in 2nd or 3rd and its like a rapid hesitation... almsot like the clutch is slipping (but thats not it)... I think it could be a dirty MAF or TB. I was going to try and clean them and see whats up
