Well I've searched and google searched but my question is still unanswered. My car's idle is pretty bad. When I turn on the A/C it goes to like 700 RPMs and back to 1000. Even with the A/C off it still idles pretty bad. I know this is the ISC but I also have white/grey smoke. This smoke only appears after the car has warmed up a bit. I'd say ~5mins or less.
When I go WOT my friend said there was no smoke. But when I idle there is smoke. Can this be caused by the ISC as well? Or can this be a bad turbo seal,valve cover,valve stem seal,headgasket? I have yet to do a compression and leak down test. The guy that I bought it from calms that it's the ISC. What do you guys think?
