82 O2 Sensor question?
I've been doing a couple odds and ends to my 82 lately and recently it's been running really rich and finally the CES light came on and came up O2 sensor rich which was not surprising. However while working on my brakes and booster I disconnected the battery and tonight when finished hooked the batt back up went for a drive. Check eng. light came back on right at start up but here's the part I don't understand, the car ran great! How can that be having a fault in the ECM and run that good?
