SPORATIC HESITATION

1996 Dodge Caravan

Engine Performance problem
1996 Dodge Caravan 4 cyl Front Wheel Drive Automatic 128, 00 miles

Sporatically while driving at a constant rate of speed around 60 mph the engine hesitates for a second or so before resuming the speed. There are no problems recorded on the computer or on the code recorder. I have recently changed: catalytic convertor, spark plugs, spark plug wires, coil, and fuel filter.

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
