idle problems

Thanks for the reply. I was wondering if the big 3"exhaust that I have on the car would have something to do with it. It is a drager exhaust from hks. I have 3" downpipe to. When it idles about 800 the exhaust starts to sweat and it starts blowing white smoke. When I idle it up to about 1000rpm the sweat goes away and the smoking stops. Is it possible that at 800 rpm that the exhaust is not flowing fast enough causing the pipe to heat up and sweat. Going back to what you said about the isc. When I replace my tps I had to take the isc off to get to the tps. I figured while I had it off that I would check the opening and closing of the isc and the resistance. It all checked out but I did not exam it for cracks like you said. Just curious what you think.
