my fd has been idling very rough. Before the white smoke from the exhaust would clear up after alittle warm up on a cold day. But now the white smoke has gotten alot worst since i put intakes and high flow cat with catback exhaust. It seems to be spuddering abit too or knock i would say coming from the exhaust. I smell heavy gasoline too coming out from the exhaust. Some fd owners have reported gasoline smell when the do an oil change but nothing like what I m having. Car would shake like crazy and it's idling around 1000rpm. I put in the pfc and commander to see if it would help but car wouldn't start so i'll prob just put the stock ecu back to see if there is any other solution. Any info would help thanks.

oh btw I already did my tune up and put msi racing spark plug wires and denso iridium spark plugs.

that is probably turbo problem. Engine oil runs through turbo. If you used thin oil like 5-30, it may cause worn bearings in the turbo. then, oil leaks to exhaust manifold. the exhaust gas burns oil. that's why you are getting white smoke from muffler. use thicker oil 20-50 Castrol. I am using this now, and it is good. you better check the turbo. i had the same problem before.

whoops didn't mean msi i meant magnecore and yeah the old spark plugs were pitch black when I took them out.

my 94 with about 85k miles does that after sitting for 2 weeks or so. Maybe a leaky injector???? After it warms up, the idle smoothes out and the smoke eventually goes away. No sign of it again untill the car sits for another 2 weeks or so.
