Trouble Understanding Codes
2012 Caprice 3.6 v-6
I have been getting the P0174 code, I have changed all 4 o2 sensors and the cam sensors ( previous code for the right bank intake sensor) I have also checked for vacuum leaks and everything seems ok. Currently and I am stuck, Dose anybody have any ideas ?

Any Aftermarket stuff on the Car?

Since it is only bank 2 I would say MAF is not the culprit but would probably give it a good cleaning anyway.

May have to do a smoke check to see if any intake seals are bad.
