everytime turn on ac car idles up and down at stop
 

lately this been happening. everytime i turn on my ac my car idles up and down when i'm at a stop or if i'm in trafic. its ok when i press on the gas. i'm wondering what problem is this. i have ls engine swap on 94 civic. i have one amp 75x4 rms. i thought it was alternator so i checked it at autozone but they say its ok for now. ( i'm not sure if he meant it or he was joking). what do yall think the problem is.. if i have no ac the car idles fine

thats an easy one, turn the idle up.
--either by the throttle cable, or by the adjuster screw at the top of your throttle body.

*edit* your thinkin to hard about it.

tighten alternator belt...could be that the alternator is due for a rebuild.

I'm 99% sure that this is normal...

does it kept on jumping up and down or just go up once then come back down.??

it will stay idling up and down. sometimes it'll shut off the car.

Isn't there a sensor on hondas that tells the car to idle up when the a/c is running? I'm not really completely sure, and I make no claims to be a honda expert. :P

i had the same problem, i fixed it by removing the a/c and replacing it with a turbo. ;)

i mother fucked that ---- for like a year, i couldnt figure it out.
