Last night I took my car off the dyno and it had an idleing problem. If the AC is turned on the car will stall and if the AC is off it idles fine. I was curious to see if anyone can shed some light on the subject. It did throw a code that read p133 slow reading of O2 sensor or something close to that. I cleared it and checked the harness of the O2 and it never came back. Any clues?
