I have a 2010 Camaro 3.6L having issues with it rough idling and smell of fuel have some white smoke from exhaust I taken it to mechanics and no luck ran me for money replaced spark plugs recently not sure what I can do any ideas thanks
Are you sure it's white smoke and not just steam from condensation building up in exhaust. If it's white smoke It can be your head gasket is bad. Is there a check engine light. Rough idle and smell of fuel can be faulty injector, coil pack, spark plug wire , ecu/pcm, map, maf, O2 there are a lot more possibilities.
I'm leaning towards head gasket if it's actually white smoke coming out of exhaust. . Easiest way to diagnose is to buy a block test kit. Your crank case positive valve or pcv can be at fault as well.
