Hi I have a 93 f150 5.0 going down hill its surging and going uphill when the rpms are low it will act like the switch has been turned off and if you let up on the gas it will pick right back up and go but if you mash down on the gas it wont run. And shifts into gear hard when its running bad, ive changed the plugs, plug wires, fuel filter. Can you please help me with this its making me crazy.
