I've said it before and so have many others... What kind of spark plugs are you using? If they're Champions, try a set of Autolites. They cured my problems with pinging and fouling as simple as that, and I've never bought a Champion plug again. I use Autolites in all my older Mopars and am 100% satisfied. Try it and see!
