HOW CAN I FIX NON ACCELERATION, SHUTS OFF WHILE DRIVING, POOR GAS MILEAGE TO THIS VEHICLE?

2003 Lincoln Navigator • 150,000 miles

When I drive the vehicle it doesn't accelerate and it shuts off while I'm driving and it has poor gas mileage.

Do you have a check engine light?

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.
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 and keep testing.
