Could be a number of things, exhaust leak, bad 02, plug, wire, vac leak, dirty maf, ect.

Last summer I put in ceramic coated LT headers and an SLP loudmouth exhaust with no cat....could that burn up O2 sensors?

Front O2 helps the engine run, the rears(after the cat) only test your cats. Chances are since you have no cat, your rear O2 is turned off so even if they somehow were damaged, it wouldn't matter.

I've only had my GTO about a month so I don't know if this helps. Maybe throttle position sensor? My SRT-4 did something similar and the wiring to the tps was bad.
