OK, basically what is happening is the car stumbles all over itself. Its a 5 speed car, and form a stop, if you dump the clutch and floor it, you get a loup Bang form the drivers side cylinder bank. It doesnt do this if you ease into throttle. Also, while cruising, at apporx 35-45 mph, usually in 3rd or 4th, if oyu floor it, it again has the loud pop, and then seems to misfire for a bit after that. There is nbo pop or misfireig if you downshift frist, before applying full throttle. The backfiring is not always accompanied by a SES light. I have read that if the O2 sensor goes in the 3.4L engines, the ECM automatically runs it rich, as opposed to a lean condition. Is this true? COuld a bad o2 be my culprit?
For the record, Mods include: KN CAI, Flowmaster cat back. doubt any of these would affect it, but who knows.
Also, the cat. converter is gutted, however I think my o2 sensor is before the cat, so that would not matter. Any suggestions are welcome! Im tired of driving the thing this way.
