Stumble and shaking
89 F-150, 4x4, 4.9 with 4 speed.
For the last year or so i would feel a hesitation when i came out of a corner and mashed the gas pedel, it would come out under full power then a 1/2 second dead spot then full power again. This problem has gotten worse in the last week and now it is very under powered even at quarter throttle. when I leave a stop light or am at the bottom of any gear it has a real bad buffering like stumble in the moter, it will smooth out once you reach speed or high RMP's and back off the pedal.
I have replaced the fuel filter and cap, plugs, rotar and wires but it did not change anything. Any help would be great!!!
