ENGINE SPUTTERING AT ACCELERATION

2000 Daewoo Leganza • 4 cylinder FWD Automatic •

Hi I have a probem with my car it starts and all but at acceleration it sputters. Like at a stop light when green I step on the gas its like its gaspingfor air and the throttle is pressed all the way. Then it will eventually pick up its normal speed. Its only at stop and then accelerate is where the problems at. Do you have any recom endations
to this problem. Tanks

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.
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 and keep testing.
