my car seems to "bog down" when i come out of 1st gear or barely push in the gas pedal. after you get going 3rd gear and up its fine. i changed the fuel filter, fuel pump, plugs and wires and put in fuel injection cleaner. this started about 3 weeks after i bought it. first it wouldnt go at all but once i done the work previously listed its better but still tries to cut out. what else can i look into doing to solve this. i hate to put more money in it and it still not run right.

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.
