My 97 mustang is running rich and I dont know why. I have changed my o2 sensors and my spark plugs and my fuel pressure is in the norm. I dont know what else to check. Someone please tell me what else could be making my engine in bank one and bank two be registering rich. I also have cleared my codes after o2 and spark plug change and my check engine light came back on after a few hours and my rich codes were back. What should I do?

Check ur ignition module if ur not getting enough spark it could cause you to run rich.

i would also check all your vacume lines,esp to your map sensor..a bad signal to the map sensor can make it run rich and only codes you will get is rich codes
