I have a 88 ford f350 with a 351 efi v8. Engine will not rev past 3200 rpm, starts to missfire badly. This happens under light load or heavy load ( towing a trailer ) Up to 3000 rpm the engine runs strong even under full load. Any thoughts, ideas ?? Coil breaking down, distributor module malfunction ? Check engine light is not on and shows no fault codes.
