Well, the title says it all.... I have an idle sputter/misfire. It runs great other than that. New plugs wires, rebuilt motor, cam timing is good, I don’t know what else could be going on. No vacuum leaks. Timing is good. What could be causing this? It spits and sputters at idle and it’s driving me nuts! I’m not sure where else to go. Is this a common issue? Any ideas? No CEL.
