Engine/Electrical problems
I have a 1993 F-150 351 5.8L V8 EFI and i am having problems. When ever I start driving, and it starts to warm up the engine starts to miss out. Causing jerking. I went through and replace the plugs, wires, rotor, and distrubutor cap, but the problem is still there. What could the problem be???

There are several sensors that might be the culprit. They don't take effect untill the engines warms up enough to get out of closed loop. Oxygen, Intake air temp, water temp maybe even the knock sensor.

If you think it could be a failed sensor, you could read the codes from the computer.
And if it will idle ok, but start to miss when you push the gas pedal, I would also agree with looking at the fuel filter.
