That's pretty much the only way I can describe the sound pffft. Rarely it'll happen during idle(idling then random pffft then idle again) but happens all the time as the revs come back down after I blip the throttle in idle(pfft pfft pfft pfft until back to idle). I don't notice the noise while driving though. I guess it almost sounds like the engine is missing? Timing is correct, TPS has already been adjusted using both a multimeter and by using the two lights.

I also have a other issue.

My idle is usually at 850 if I rev the engine anywhere over 1000 it'll stay slightly above 1000 when the idle drops back down. It doesn't go back to 850... I adjusted the variable resister or air/fuel module on the pass side engine bay and that seems to bring my idle down to 850 after I rev the engine over 1000 but I'm not sure if what I did actually fixed the issue. I use to turn on the headlights, FTP's and brakelights to get my idle back down to 850.



If I have to I'll make a video of what I'm trying to describe.
