I just changed the O2 sensors. Did not fix the issue. No vac leaks that I can tell. IAC has been changed. Took apart MAF and cleaned it (wasn't even dirty). What else could this be? Code 11's when I run the scanner.

So when does the light come on? When does it go away?

What sort of scanner are you using to read codes. Does it have a cable that will reach into the cabin with the hood closed.

I used to have the intermittent check engine light way back, turned out to be the egr.
Cleaned all the carbon and soot out of it and it went away.

seems like light comes on when it is colder in the morning. It will come on for a couple second then off then repeat. Seems like when I accelerate it comes on. I used a scanner that puts the numbers on the led screen so no room for error. Nothing that will reach the cabin. Car runs and idles perfect.

Accelerate at WOT? Or part throttle?

Seems like any throttle. But not every time.
