My gt have nothing but problem these days, last Friday I was coming home from work and did a some hard drive and now my car is miss firing . My exhaust tone is completely different and sounds like subaru sti exhaust.

When I park I can smell bad odor, is my cats of my upr x-pipe cloged or something else it wrong ?

Car got half the power it did , what should I do ? where should I look ?

Last time I had a bad bog problem and fiexed it after I change both front 02 sensor and all coil on plugs with accell.

Need help please, soon to be sold.
Just sick and tired of my gt

cats could be clogged...

I've heard nothing but bad things about the Accel COPs...pull codes and try to narrow it down to specific cylinders?

watch the COPS while the engine is idling. If any are vibrating bad, a plug may have blown out or you may have a ripped boot.
