Car is smoking at idel.
Hey guys this sucks....My 93 Touring seems to be smoking at idel...the color of the smoke is gray meaning oil. And It'll smoke when the car sits and idels for a few minutes. The smoke amount isn't a crap load but its not little. The Turbos were replaced about 17k ago. Not sure if they were rebuilt or new. I have the airpump removed but with upgraded ECU and Super AFC (from RX7.com) to subtract fuel from idel to help smooth out the idel. The car seems to run strong. What I did notice before was when ever I would screw with the idel adjustment the car would smoke alittle but just for a few start and park cycles and it would go away. I pulled off the turbo inlet tubes and very little oil residue....pulled off the plastic elbow by throttle body and no oil residue. O forgot to mention I had just finished replacing both throttle body gaskets, added an extra ground using one of the throttle body nuts, and changed the oil using what I've always used Royal Purple synthetic 20-50 with OE filter, and thats when the smoking started. The original paper gasket on the throttle body was really in bad shape it was actually missing a chunk replaced with metal OE. Maybe the turbos on the exhaust side is leaking the oil and burning it. dunno I hope u experts out there have an idea. P.S. sorry for the thread length. Thanx... Tony

If I read you correctly, the smoking started when you changed to synthetic? If so, maybe you want to see what happens if you switch back. Are you losing oil?
BTW, I think the ecu relearns and adjusts itself when ever you change idle screw and other settings.
