My car is throwing some codes - one was a bad precat O2 sensor so I swapped them and sure enough it popped up again in its new home so I replaced it, no issue there (Thanks to advice from this forum). Now I have two additional codes, P0171 and P0174, bank 1 and bank 2 too lean. There are several possible reasons for the two codes, most likely is a vacuum leak and I'm chasing that down.
The cam timing error after an IMS bearing install you have is in a whole different league. It makes me think the valve timing has slipped, i.e the cam chain is a tooth off. If it were me I would not run the engine anymore. I'd pin the engine at TDC and check the valve timing with a timing tool. Either it is correct and you can move on to something else or re-adjust it and you are done. Otherwise you risk valve/piston interference which is catastrophic.
