Changed injector, coil pack good, replaced injector connecter, checked for cracked wires, changed o2 downstream sensor. But codes still there after resetting. Engine still running in bad condition. What the heck? Should I change the upstream o2 sensor? Could that cause a injector circuit to stay open? Or is it just a bad computer?

I would think the PCM is the issue if you have replaced the injector and the wiring is okay. The PCM is the last thing.

I attached the testing that we need to run through in order to find out what the causes are.

Let's run through this testing and we can go from there. Thanks
