Hello there, I have been trying for 3 months to get the code light to go out so that I can do inspection. the code is system too rich bank1, p0172. I have changed the o2sensor, the air management diverter valve, and solenoid that run the air pump, and cleaned out the throttle body with carb cleaner. The service engine soon light goes off every once in a while, only for about 20 miles, then comes back on.
Any suggestions what to do next?
