last year I bought a 1981 Jaguar XJ12 V12 Vanden Plas car was made in Febuary of 1981 and I don't think it's HE, has 60,000km the guy I bought it from was either in the process of or finished installing a Crane Cam (XR700) ignition (from summit racing) he said he couldn't get injector pulse. I picked it up about a week later and he had managed to get it running by running a wire that goes from the coil to the ECU. The car now runs way to rich if I have it running (outside) my eyes water from the exhaust I stopped running it after I found it was running so rich that I think there was gas in my oil and the chrome bumper had soot on it. I need help would it be the ignition doing this why does it run with the wire but not without? Thanks in advance
