92 F150 4.9 rough running
I'm stuck, I got a 92 with a 4.9 I inherited from my father in law. It's been sitting for several years and only has 135,000 on it. It runs rough like a miss and black smoke. I've drained the old fuel and cleaned the tank, new injectors, map sensor, everything associated with the egr, fuel pressure regulator, plugs, wires, cap and button, got an ecm from rock auto, all vacuum lines and can are good. What do I try next, I don't want to take it to a garage. Please help!!
