so my girlfriend just bought a Crown Victoria for her first car. It has a miss in the engine. I have changed the spark plugs in it and its still there. Also there is a hesitation under medium acceleration. What could be the problem? Does the distributor need to be advanced up or retarded down?

Lack of acceleration,chugging,hesitating,jerking,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.
