PM Reckone he most likely has one somewhere.
My only other guess afterwards is a vacuum leak - Chryslers are notorious for having horrible misfire issues from a a vacuum leak.
That’s all presuming your distributor is in fine working order.
A vaccum leak anywhere past your MAF or MAP/MAT sensors would cause the engine to have a completely improper mixture from what it’s expecting to have. Culprits are sometimes an intake plenum gasket leaking in extra air, or any of the lines connecting to the manifold. Check for flexibility in them and dry rot.
