and then check your car where the headers meet the first part of the exhaust system. It is said that if there is a leak there air gets sucked IN and gives that post O2 sensor false readings.
Have you checked for vac. leaks yet? You make a decent smoke tester with a cigar and manual pump for $6 from Harbor freight |

Yeah, had already smoked the engine.
No leaks anywhere.
