Have a 94 ford van 351 that is used as a church van. Engine has developed a miss in the engine when it gets hot. Have replaced the plugs, wires,fuel filter, coil pac. Runs good wide open. Seems miss is worse while engine is under no strain, just cruising. Runs good at half throttle. Any suggestions would be helpful.
