My 04 mustang GT has a check engine light from the 02 sensor. It has aftermarket exhaust on it causing it to trip the O2 sensor. I can tell its running rich on fuel also. What is the best way to handle this? I like the aftermarket pipes but my concern is for the health of the engine. What do you recommend?
have the same problem?
