that's my fear as well - when we unplugged the MAF, it seemed to run better...
I let the car idle for a couple minutes and it didn't get any better/worse. The AFRS were moving but were REALLY weird: started initially below 7.4 (so it would just flash at me), then at part throttle shoot to 21.8 instantly, despite the exhaust still blowing black (so there's NO WAY it was that lean). I probably fried the 02 somehow, but have another problem too
