After i had gotten a dual alternator pully installed, when i free-revv the car in neutral it's as if there's a stutter box or rev limiter set at 5000rpm, the car hesitates there when revved and on light throttle....

if i drove gingerly through 5000rpm the car bucks like crazy and falls on it's nose, but if i pin it, it runs fine....

any idea's?...

 

Sounds like a bad electrical connection to me, either with fuel or injectors. I would say bad grounds, but it could also be a injector clip is lose/disconnected.

 

i re-grounded my WHOLE car, made sure the injector clips were tight and snug, and re-checked them all once more....

it started after the car had gotten the dual-alt pully installed....

:S

 

anyone!?
