I have a 93 ATX, 3.2L. It is hard to start after it warms up, some of the time. I've replaced the timing belt, CPS, CID, valve cover gaskets and tube seals, Spark plugs, possibly inferior ones, and spark plug wires. When I say its hard to start, it seems to spit and sputter until I rev it up for a moment or so. Any ideas? Any help would be greatly appreciated. Thanks Charles Meador
