I have numerous problems with my car, and try to fix them as the come up, but this one keeps baffleing me. After coming to a stop, I press the gas pedal and the car hesitates for about 30 secs, then slowly begins to increase speed while the rpms are high. Then the car "chugs and sputters" back and forth like the engine is going to die, then jumps wide open driving fine. We have just replaced the fuel filter and fuel pump at recommendation of the mechanic, but I am still having problems. Please help!

Has the check engine light ever come on? IF your car has A Mass Airflow Sensor, which I think it does attached to the air filter box, look for cracks in the big tube from the MAF to the throttle body. If it has cracks it will open them up when you hit the throttle and cause the mixture to change.

Hello,

Check the Tranny Fluid.

Make sure it is showing full

Look at the color - is it red or pinkish looking or does it look brownish.

Smell the fluid - does it have a burnt smell to it?

If fluid is brownish and smells burnt you will need to have the fluid and filter changed.

Next is engine light on? if so follow directions below to retrieve codes and post them here....

To extract DTCs from the computer for diagnostic purposes, the Self Test connector is used.

1.Start engine and bring to normal operating temperature. If engine will not start or stalls after starting, proceed with next step.
2.Turn the key "OFF", then wait ten seconds.
3.Activate the self test by grounding the Self-Test Input (STI) connector.
4.Turn the ignition key "ON".
5.Record all codes received.
6.Turn ignition "OFF".
