I have a 92 s13, stock KA. I noticed the car doing this a few months ago.

When I sit at idle for a few seconds.. maybe 15 seconds, I can rev up the car and it throws a LOT of gray smoke out.. it's a lighter gray. I read online that it may be running rich, but I have no other symptoms than that. The car runs great, and has no noises or other problems at all.

The only thing I can thing of.. The O2 sensor wire hit the header and the insulation got burned off a bit, but the actual wire inside is fine. Could this be causing it or could it be something else?
