Just noticed you were running the S/C at one point (assuming form your signature). I recently pulled the exhaust manifold off my buddy's TC that was running the S/C for a while and the carbon build-up on the exhaust valves was terrible. Maybe that is your problem.

 

^ yea i had the cel and fixed it in the o2 bank 2 - carbon where - in the cat?

 

my issue is - its not doing it till the car is real warm ..... so its cant show anybody cause its not happening then

 

I still say pull of your exhaust manifold and check out the cat and the valves. There is probably a lot of build-up in there. Not sure why it would happen during warm conditions only. Did you clean your MAF?

 

^ forget the warm condition - i think that was just bad luck and not a trend. i went to work today and no issue. what is the proper procedure for cleaning a sensor? last thing i want to do is mess them up since they cost so darn much.

 

Umm, I would have to say that carb cleaner would work? They sell whats called "Mass Air Flow Sensor Cleaner" at Autozone. Try that stuff before carb cleaner.

 

^ cool - thanks for the help

 

No problem!
