well, i thought it was my alternator, whenever i start up my car it'll almost die when regularly idling, i have to keep my foot on the gas when i start it up in the mornings, and now in the afternoon sometimes; but even then the idle will move up and down. Then when i start to drive i'll hit the gas, i'll start going a lil bit and then my car will almost just cut off and the accelleration is gone. within a second it'll come back. any idea waht this could be? Please help. I think this other problem im having is linked to it. well whenever i try to rev my engine sometimes it hesitates too. or when i rev it my lights will start to dim; just a lil. When im accellerating my car seems to HESITATE ALOT and i lose ALOT of power. it sucks. but could my alternator cause this, i thought of it as it because whenever im flooring it its using more power and making the alternator work harder. im just wanting to make sure before i go and buy this damn alternator. others said it could be my Mass Air Flow Sensor? any suggestions on waht to try? i replaced all my fuel lines and vaccum hoses recently, and no change.
well, i found out that my lights dim whenever i had my car off and my subs blaring. but you had the problem with the accelleration as well? and it was the Idle Control Valve..hmmmm. didn't know that was linked to accelleration
OHH YEAH! and i realized today, when my cars driving and idling it'll be rite about 500rpm's and just sit there and jump 100 up and down up and down whenever in neutral or regular idling..did u have that same prob?
the problem i had was the car would idle fine in park, then i'd shift into drive and it would start shuttering and dipping down to 500 rpm, back up to 1100, and continue to flutter... as I accelerated, it felt like no power and had a hard time climbing up in RPM then it was fine, but it only did this when it was cold.. most of the time it would cure itself within a minute, sometimes it lasted a little while longer.
