Winter before last on the 06, I was was fighting CEL, I forget the number off the top of my head. It was when the car first starts, it turns on a blower and opens a valve to dumps oxygen into the exhaust to check that the 02 are reacting. That motor only comes on for a few seconds, so my GM buddy brought home his gadget. While the car was off, we could command the blower on, open and close the valve and listen at the exhaust. All seemed OK. Then started the car and would do the same test, while watching the 02. All seemed ok. I replaced the valve as a shot gun fix, did not fix it. Then summer came and it quit throwing the code. So I waited this winter, still no code. I was suspecting the heater on the 02 is not functioning correctly, and once the car starts it works. Thats another thread, the point is this all can't be magic. The time and money I am spending on this is nothing compared to what I spent on college to learn, and this is a lot more fun. :-)
