I think that the spots are as u say just condensation and carbon from ur exhaust valves,cat,pipe and muffler.The idle roughness is what u should work on now that the miss is gone.I dont know what kind of plugs u r running but whatever they ate,try gapping them 2 thousands more than spec and see if that might smooth out yr idle,since ur running a hotter coil,taht might burn off enough more gas to smooth things out a little.BJ
