This has been going on for quite a while now... So usually when my car is warmed up it idles at about 700-800 rpm... whenever i turn my a/c on on a hot day and am standing in traffic in neutral the car idles rough where my rpms drop to 500 rpm then go back up to 800... this is happening constantly... this only happens when the a/c is on... My car does not have any known problems and the new maf has only 1000 miles or so on it...

so any suggestions?

 

IACV's the problem

 

ok.....

 

He means your idle air control valve might be malfunctioning........

It could be something as simple as the fans pullin alot of currents when they switch on, thus dropping your rpms to .5k. It happens to me sometimes, i most likely need a grounding kit to fix my problem.

 

thanx guys i will check it out. This is nothing serious?
