Yup, that's the exact article I used to install the Holley, and like I said it ran fine until just recently. One of the injectors was leaking, not sure how long, which fouled the plugs. I'm guessing that is what fouled them. I used that wiring diagram to install it, but just for arguments sake, would it work if I DID somehow wire it wrong?
