p1153 code and speedometer needle bounces on braking My car a 1996 base Camaro recently threw a P1153 code suggesting an O2 sensor (bank 2 sensor 1) is either bad, or detected something.
Simultaneously, the speedometer needle started jumping or wiggling really, when I brake, or even turn on the blinkers, suggesting an electrical problem.
I recently replaced the compressor in this car. It required removing the engine ground connector. I believe the connector is tight, but should I try another ground wire to be sure? Could I have damaged a wire or sensor? Any suggestions appreciated.

I cleared the code and so far the service engine soon light has stayed off. But my speedo needle still wobbles rapidly (>1-sec) when I hit the brakes.
Is this a symptom of a grounding problem?
