gmsracing Posted August 28, 2005 Share Posted August 28, 2005 Upon acceleration I noticed billows of white smoke out the exhaust and very rough idling as if car wants to stall. Doesnt smell like antifreeze or oil. Its a strong smell of gas. I am reading that it could be blown head gasket, injector issue, faulty O2 sensor, etc.,. Didnt notice any antifreeze on oil cap and nothing looks different in coolant. Any ideas. Thanks. Quote Link to comment Share on other sites More sharing options...

don_juan_miami Posted May 9, 2006 Share Posted May 9, 2006 ignition coil? i have the same prob with my car... i drove it really hard to work one day ( running late ) and then that night when i turned it on... mass amounts of smoke out of the exhaust... white and smelled like crap. Popular consensus was that it was a blown head gasket... Then i got a guy a the bar ( im a bartender) from out of town, said it is really hard to blow that gasket, on a N/A totally spec 2JZ-GE... He said it is a possibility but to take it to a shop, get the radiator checked for leaks, and if its not that, to get the compression checked in all the cylinders... He said that would tell me whats wrong... havent done it yet... any help would be good tho as i am in a similar predicament Juancho Quote Link to comment Share on other sites More sharing options...
