My 93 F 150 5.0 with AOD has a miss in the engine under a light load,it appears to be alright was long as the engine is not pulling. I have tried new plugs,wires,fuel filter,distributor cap.rotor,and I took the brain off and had it checked at the parts store. Thre is no miss when shifting going from 1st to 2nd gear, but from then on the engine misses until you get into overdrive and the RPM's level off at a cruising speed.The engine will also miss in overdrive if pulling.DRIVING ME NUTS
