Possible O2 sensor bad??
I noticed when I unplugged the O2 sensor there was no trouble code set. Is this normal? It seems to run the same when the O2 sensor is unplugged. Any ideas.

when the car is just sitting at idle, there wont be any noticable difference. If its cold and in open loop, there will be absolutely no difference. the fault will need to happen more than once before the light comes on.
