my van keeps bogging when given gas. I have changed the fuel pump, fuel filter, and the fuel pressure regulator; no change in the way it runs. When van gets going it will lose pressure somewhere and car starts bogging and losing pressure and when I press on the gas it will most times do nothing. HELP PLEASE!

since this is a free question I will wait patiently for your response

Thank you for your patience-see below:

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.
