Very interesting I also installed the Vette sensors, went 140 miles with no codes, and my 1133 also came back on the following morning 5 mins after start up. I was cold as hell that morning, if the air pump only comes on at start up, this would be good evidence that it's the culprit and should be capped off. I hooked up my scanner and drove to and from work monitoring the 02's, they were both switching fine, yet the light was still on. A logical deduction would be that starting the car on a cold morning with the air pump dumping raw 02 into the engine was too much for the sensor to heat up and it kicked out a code. Minutes later when it was hot enough, the sensor started working fine but of course the light would remain on since there was an intermitent problem. What are your thought's on this? By the way, have any of you with this problem capped your air pumps?

i have been running off for a year, the logs show nominal activity on the o2's nothing different, all readiness bits ok. I figured it was the o2 extender cable since i only had one side doing it randomly. I keep an eye on the warmup pattern and closed loop of both now and then, dont see anything really different between each side so i guess it may be a picky ecu issue.

Next deduction in the logic chain
