My f150 hesitates while stoped at a red light. I press the gas peddle and hesitates to go the takes of. If I put it in nuetral or park it does not hesitate. Also at high speed (70 mph) it jerks when going up a hill I have changed the following. Spark plugs, gas filter, injectors, idle air control valve, egr, also clean egr ports in the throttle boby. Today I had a p0420. Please help
have the same problem?
