I had a 94 toyota and when the ac was on the idle would speed up. Well now I have a 92 and it does the opposite. Its gets so low that sometimes i think its gonna stall. Can anyone tell me the cause and what can I do to fix it. Thanks.
Is that the idle air valve? I was told that the IAV was probably the source of my issue (which is remarkably similar).
i have a similer Q? my idle goes up and down when ac is on like when im driving and stop at a light it fluctuates what the he**!
adjust the valve, its not set right, its prob too high, causing it to fluctuate at idle with the a/c on
Well I tried adjusting the screw and got nothing. I was told that it maybe the ac idle up solenoid, which cost 140 plus at the dealership. Is there a way to re route the vacuum lines so the engine doesnt bog when the ac is on???
