car is running really rich could old oxygen sensors be the cause. i already change plugs cap rotor. trick flow intake im still using the stock mass air. just put an msd 6al box it help but still got the raw fuel smell. if im using an h pipe with no cat are my oxygen sensors going bad. should i try to unplug them and not use them. car runs great after it warms up with the 180 stat im out of options
