I have a 94' gt with cold air intake, mac h-pipe, and mac high flow mufflers.

When the engine is cold and im driving it backfires when i give it too much throttle. it also seems like i lost a lot of horsepower. i could give it alot of throttle and it accelerates very slow. my check engine light comes on mostly when i accelerate then goes off. (this all happens when the engine is cold, when the engine warms up it drives normal but the check engine light is still on) i took it to autozone and they said an 02 sensor was running lean. so i put some chevron w/techron cleaner in and it didnt work. he also said if thats not the problem i could use bigger fuel injectors. my last tuneup was last year.

please help
