Default Re: 4.0 V6 misfire

the engine is newly rebuilt with only 50,000 or so on it, no signs of piston rings failure or wear, plugs come out clean, tad on the lean side but i believe i have fixed that with decarboing the engine with seafoam deep creep and berryman throttle body spray, right now it looks like a hunt to find the phantom problem.
