Also, sometimes it picks up its normal idle and then goes back to sputtering. If that helps any. It idles around 950 normally, but with this new smell and sputter its around 800

A guy I know said his Trans Am started running alittle rough and sputtering. He ran some SeaFoam through his engine to clean it out and was pleased with the results. Said it idles smooth again. Is it throwing any codes?

appreciate the help guys, I dont think its the fuel filter because at full throttle its fine. I'll run some seafoam again, but I did that about 3 months ago. Im thinkin its the MAF or O2s can anyone chime in if theyve had this problem?

front o2's... get the corvette rear o2's for them, bosch part # 13111 ... there i thnk like 65 or 75 a piece.
if those are bad or not working properly they will cause a problem... i had a bad one and my car was eating gas amounst other things.
the rear o2's i wouldnt bother with... they don't effect your car just give you an SES light... get em tuned out or buy some o2 sims.

Nah, its not the plug wires. It runs fine when its cold. It has to be the o2s because when it goes closed loop it idles funky. And I've had the headers on for 3 months without problems.

Ya it's your o2's same thing has happened to me a couple times, as soon as you get into the gas it clears right up. Do like 98_formula said and put the bosch part # 13111 in I haven't killed them yet.
