Hello,
We just rebuilt a 1991 Ford E150 (302 5.0L) with EFI.
We followed the rebuild procedure to spec, replaced the crank, crank barrings (which came with the re-manufactured crank), cam, lifters, oil pump, water pump, distributor cap and router. radiator and switched out to an electronic fan with thermostat. we also lightly tapped the valves with compound making sure not to take too much off.
Problem. When the engine idle kicks down the idle is VERY rough and it will eventually...
