View Full Version : Rough idle when AC is engaged

Like the title says, when I turn on my AC my idle gets jumpy, and it starts idling pretty rough. Vacuum leak maybe or something else?

It could be a vacuum leak, they're pretty common on E46s. It could also be a faulty ICV or DISA.

kk thanks, ive noticed its not just the AC being on, if any of my air setting are on it idles poorly. will have my mechanic look for the problme when it goes in for the body kit to be put on.
