so the gp i bought last night threw a CEL today.. i get home and im sitting in teh driveway @idle for 5 minutes or so.. i look in my mirror and see white smoke pouring out of the exhaust. i shut it down and let it sit for a minute. cranked the car back up and i have some pretty serious top end noise.. still dont know the code yet... but the car is under warranty and getting fixed for free.. kinda sounds like a bent valve maybe. oil doesnt look contaminated at all. however i popped my oil cap off and took a whiff and it smells strongly like gas. my first thought is o2 took a serious **** and filled cylinders up with gas. what do u guys think.
