I am experiencing a sluggish engiine when I accelerate. It seems as if the car is running out of gas even though it's full. Could it be a fuel filter? No lights or warning are on.

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

Inspect and test all the following listed below and get back with some results

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position 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.

You may want to have the fuel pressure checked to see where it is at? Also can you have the engine control module scaned for codes and if there is codes stored, can you post them on here?
