Misfire Cylinder 3

Had a "Misfire Cylinder 3" code. Rough idle, rough acceleration.

- new plugs
- new coils
- cleaned intakes
- replaced VCG (not intended to fix the misfire but it needed to be done)
- new injectors

Put it back together and "Misfire Cylinder 3". What's next? Bank 1 pre-cat O2 sensor? I just ordered one. No idea what else it could be. Wiring harness?
