So my 91 944Ts 02 sensor was bad, would slowly drop down to .00xV after start up and stay there till ECU would store 2-3-2 and 1-1-3. Bench tested the old one and it won't budge under the propane torch; new one builds to .9 and drops under a second. Put in a brand new Bosch 13957 and now it does the complete opposite, slowly climbs to .9xxV and stays till the same codes come on. So the car is running rich and that's probably what killed the other 02 (NTK brand crap anyway). So where should I start to figure out why it's running so rich? Why am I not seeing any cross counts?
It starts fine, idles fine, revs up nice. I haven't been driving it much at all, since it is in dire need of a trans mount replacement.
