Car idles fine for awile then it will miss and try to die. Replaced fuel filter, air filter, sparkplugs, and cleaned out throttle body and idle senser and mass air flow senser. Before I did all this the car was running worse, poor power. Please help

Lack of acceleration, chugging, hesitating, bogging 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.
