So I installed new headgaskets and while it was apart I installed a 73 MM C&L MAF with the stock size tube for my stock injectors and i used my old electric sensor out of the stock MAF. When i got it all back together and fixed all the vaccume leaks It runs pretty good now, but the check engine light comes on when you get on it a little, then it will go back off in a minute or two.
The CEL codes i get with the engine off and key on are:
181 C Adaptive fuel rich limit reached at part throttle, system lean, right side
185 C Mass Air Flow lower than expected
189 C Adaptive fuel rich limit reached at part throttle, system lean, left side
211 C Profile Ignition Pickup (PIP) circuit fault
I didn't think it was the oxygen sensors but with 200k on the car i figured i should go ahead and replace them, but of course it wasn't them it never is.
So my question... is this normal for a C&L MAF I understand our MAFs and EECs are complex but i don't think this would cause it too run so lean that it would throw codes.
I installed a 70mm bbk throttle body at the same time as the maf but i don't think that is the problem either
If i only had the stock MAF to swap it back in... NOTE-never give old parts away
