I think they may be linked. Last time I dealt with a weird commanded AFR problem, O2s fixed it. I am going to go pick up a new pair of 2008 sensors here in a few minutes...almost $300, but if it fixes it, so be it. If not, my wallet isn't any lighter.

Sheesh, where are you getting those from?

Oriellys, their list price is like $130 each. Probably get them a little cheaper on the business account.

They go for about half that on rockauto

Didn't turn out to be O2 sensors, so no money lost there. I think I may snag a BCM and see if I can't fix something with that lol... At the very least, it should provide the proper signal to the FPCM so I get full fueling functionality back.

It commands rich. When I can get my hands on a noid light I will verify the injectors are working properly or not. I can smell the fuel, though...

My thought was that it wasnt getting fuel and that it was trying to compensate.
