Do you recommend me getting Acdelco 02 sensors or what sensor do you recommend?

No the genuine gm oem are not in it. They were TRQ OSA61839. And the injectors I got from advanced auto brand car quest. The shop was concerned about that and replaced the injector on the cylinder that was showing misfire with an oem one and there was no change. I realize now after putting the parts in that I should have went oem.

What does this site do?

I have brought it back to them multiple times each time they can’t figure it out or they tell me it’s fixed but when I pick it up it’s still not fixed. I picked it up without check engine light (still running rough) and 5 miles down the road it comes back on. The last time they looked at it they said that the issue was the 02 sensors were not OE so I brought it to a dealer to put OE 02 sensor in it and they said my 02 sensors are fine and the dealer wrote scanned codes and it has codes for p219a and p219b fuel trim cylinder balance both banks, watching misfires it is misfiring on cylinders 1,4,6,7 which are all AFM cylinders, looked at AFM data and everything is reading malfunction which is what is disabling the injectors for 1,4,6,7 causing the cylinder balance codes, customer stated the truck has an afm delete kit, either there is a problem with the delete kit or the tuning because the delete kit is causing the injectors to shut off. i brought this up to the shop that did the motor and they said they don’t know how this is possible. I had a tuner come out to confirm the tuning was correct and it is. Sorry for the small text I’m not sure how that happened.

Recently I had my lifters collapse and i brought it to a shop and they put a new motor in it with the AFM/Dod delete. Ever since I’ve had a check engine light for P219A P219B PO300 that I can’t figure out. It drives fine but at idle it has a rough shake. The truck has new coils,wires,plugs. New injectors New 02 sensors New high pressure fuel pump. New exhaust manifold gaskets. I cleaned the maf sensor and throttle body. I sprayed brake clean around the intake gaskets and there was no change in idle. I did a compression test and cylinders 1,4,6,7 have 180 psi and 2,3,5,8 have 210 is this normal? Any information helps.
