i know this thread is use enough but heres another, my idles surges only at operating temp, with the a/c off it still stutters a little, as soon as u turn it on, it runs like ****, i don't have any Cels, and timing is dead on, i've kinda narrowed it down to my iavc or my msd ignition and i know i don't have any vaccum leaks, any other ideas??

Well with the A/C the computer is sapossed to bump your idle up a bit to compensate for the extra draw. About all I can think of at the moment.

thats the thing it trys and it throws it back down, and stutters and go backs up, it only goes up and down about 3-400 rpms but its enough to make my car stutter

Check your motor and tranny mounts.

I don't think it's anythign to worry about, the a/f might be a bit high or something stupid like that..

I mean how often do you turn ur air conditioner on at idle and sit there for awhile?

D15Bbigred

well it does it slightly when the car is just sitting at a stop light with the a/c off, when i start off my idle is rough untile i hit 2000rpm and then the car drives fine
