Helping out a buddy. He had a bad engine vibration, bought the car that way. He is pulling the motor and it looks like 4/7 cylinders were never working. Other than plug wires incorrect, what would cause this?
I wouldn't think it would have even ran this way. He said the vibration was pretty constant but would decrease at certain rpms. He already removed all the plug wires, so there is no way now to see if it was wired wrong and engine is about pulled so can't just quick put it together to check.
Any thoughts on what else to check?
