Re: Build & swap of a SBC in a GMT800

Double check you don't have a fualty O2 sensor by puting them in each others places.

Pull your plugs and make sure they all look the same.

If you have a plug that is not firing, it's going to skew the one side to show extreamly rich in comparison to the "lean" bank when in all reality, both banks would be lean if that one plug was firing properly.

Sounds like you have a data logger, log misfires. What ever cyl has the highest count of them, start there.
