Engine Performance problem
1996 Ford Explorer 6 cyl Four Wheel Drive Automatic

I have replaced all the things that I have been told could be the problem. I have replaced the crankshaft position sensor, the egr valve and the mass air flow sensor and it is still bucking when I hit 80 mph. Please help me

Lack of acceleration, chugging, hesitating, bogging, misfiring etc. Could be caused by one of the following below:

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard it.

Ok apparently you know nothing about a 96 ford. I do not have a cap and rotor. It is just a coil. I siad it was bucking at 80 mph, everything else is fine. Please do not provide such a general answer. If you are unsure, do yourself a favor and maybe ask someone before you answer my question. I do appreciate the speedy response, but not satisfied at all.

Maybe if you start troubleshooting the general answers that I gave you -you might get somewhere instead of coming back and telling me you don't have a cap and rotor, I was prepared to help you all the way to fix your problem now I've changed my mind-Good Luck
