my car is exhibiting idle problems when the AC is on, this problem recently occured the car never had any idle problem of any type before this. when i rev the car at dead stops with the AC on, the car would bog down to 100 rpm then recover at 500 rpm where it should always be, but when the car is in motion everything feels fine, no power loss, vtec feels fine, and also the idle sound a lil rough. what is going on?
plz give fed back.thx...

lil help here

 

there is a million sensors w/the a/c system. one tells the ecu to up the duty cycle of the iac valve when a/c is on, so it doesnt bog and die. it could be something like that.

 

ANYMORE?

 

Ive had the problem for about 2 years, whenever its hot and the ac is on and you're stopped the rpms jump. I have just gotten used to it, I think its just the a/c trying to work hard with the 4 banger? but im not sure of any mechanical probs.
