Alright well last week i put on a new TB and new tps and iac sensors and the car ran great. Now tonight i went to take it out cause i only drive it on fridays and saturdays to the hang outs and whenever i floor it SOMETIMES the wideband will read 12.0ish and dump madd fuel out the back. Now im alittle over on a oil change but i wouldn't think that would cause that would it? I revved it up at idle and sometimes it will throw back blueish smoke as if it's oil to. Anyone know what could be going on cause its only doing it randomly and the car does feel alot sluggish. Thanks.

Head gasket, worn rings, valve stem seals. would be my guess check your oil level make sure its not over filled.

look over the oil to air sep box, they like to clog up. and i hope you still have it hooked up to allow for crank case vacuum......

but GM is known for having @!#$ty valve seals...


also a extremely rich burn can cause black\blueish smoke..... try leaning it out?
