V8 missing

Ok, head gaskets done, waterpump replaced, bloody things is running like a pig, put obd2 computer on it and no codes. No codes for misfire or injector circuit codes ? Any ideas? Going to change leads and plugs anyway.

D2's run coil packs, there's probably some leads swapped around or a connector plug off somewhere.

I was going to suggest that, but you can lift the coil packs out without removing the leads, so unless you were replacing the leads they probably didnt get mixed up.

The coil packs run off the black plugs and the step motor uses the grey one, I accidently plugged the grey one into the coil pack when I replaced the motor.

I had my v8 mis firing at one stage. I replaced the coil packs and put new leads on it...It now runs beautifully. When i took the old coils out, i noticed one terminal was fairly badly corroded, and the corresponding lead was pretty toast, so maybe just one coil pack would have fixed it, but for the sake of not having to get back in there, I replaced both!
I had no codes on my obd11 reader either.

Plug leads arse about. Will order leads from roverlord in new year now.
