[s14drifter86]

hey guys im new to the forum but i cant figure this out my car dosent smoke or anything driving but when the car sits at idle for about 5 mins or so and i blip the throttle i get a decent cloud of a whitish smoke .... really doesnt smell like oil but the motor in the car came from an auto transmission car so the tps is diffrent than that on a manuel transmission so im reading off the mass air so car runs a little rich and throttle responce is not all that great could this be the problem??? and also motor runs and feels strong under heavy throttle or just regular throttle but when coast and im using like 10% throttle car jumps a tad im thinking maybe this is also because of the TPS can anyone help??? just for info its stock ka (planning on going sr next year so why bother) only thing done that will change numbers is i am running a 3in cat and 3in stainless steel exhaust (for when i go sr)
