I’ll spare you all the long details of everything, I own a number of vehicles and rent them commercially and personally. I have not seen my suburban for six months as well. Last I was able to contact the person renting it was in December when they installed a new motor mount. I had to repossessed the car and it’s running pretty rough right now. There are 21 faults and I’ve whittle down some of the problems.P0030 ho2s heater control circuit bank 1

P0031 ho2s heater control circuit low bank one

sensor one

P0050 bank 2 sensor 1

P0051 bank2 sensor 1

P0443 evaporative emission system, purge control valve circuit

PO458 evaporative emissions system, purge control valve circuit low

PO6DA manufacturer control

P3403 cylinder one deactivation intake valve circuit low

P3427 cylinder 4 deactivation

P3443 cylinder 6 deactivation

P3451 cylinder 7 deactivation

I know this is only 11 but most faults have two codes thrown for the same issue so I’ll save room.

1 4 6 7 cylinders means cylinder deactivation cylinders are the failing ones.

But then there’s knock sensors and O2 sensors going off as well. Anybody ever have an issue like this or have any clue as to where I should start?
