1985 S3 - L-Jet.
I have been running the car with very rich mixture, I suspected the reason was a faulty Fuel Pressure Regulator. I replaced it along with spark plugs, new vacuum hoses...etc. At this point my Cat glows really red hot, and the car buck. I what thinking of using Lucas Fuel Inject cleaner... to possibly help the fuel injects and the rest of the engine, before i replace the Cat Converter.
What do you guys think about the Cleaner??
