But O2 sensor and MAF with the above??? very doubtful.
I would look at a wiring schematic and see if they have a common ground.
A bad common ground for the circuits or for the ECU "could" cause your issue.

I saw another thread where the issue looked to be pretty identical to what I’m experiencing, from 2007, they said they re established the ground from the MAF which was pin c9 on the ecu, but I can’t seem to find the pin out for the ecu anywhere, and also don’t really understand what it means exactly.
When I unplugged the MAF the car wouldn’t fire at all.
I reset the codes and the o2 sensor codes went away but everything else remained. I highly doubt this is something as simple as a fuse but I suppose I should check them just for good measure
