the problem isn't fixed yet but I was able to get codes from my car by stepping the gas down all the way five times, with key in run, within 5 seconds, and count the four digit codes. 1221 kept repating. That means the O2 sensor is bad. Also 1211, which means the O2 sensor has bounced off it's limits. That makes sense because of the rich condition making it rev up. I also learned from Mr. Bently that the O2 sensor is heated to 600F+ before it starts sending signals.
