1996 Oldsmobile Ciera Repair Question
1996 Oldsmobile Ciera acceleration
1996 Oldsmobile Ciera 6 cyl Front Wheel Drive Automatic 90000 miles
My car has problems accelerating. When in park/neutral it will rev about 50% of the time with no problems. The other 50% of the time, it sputters and backfires and eventually starts to rev without problems.
When in gear, however, i have to lightly feather the gas pedal to get the vehicle to move. (If I floor the pedal, there is no response at all.) Even when lightly feathering the gas pedal, the car will still buck, sputter and backfire sometimes. Going up hills it takes the car a while to shift to third gear unless I let off the gas pedal, but then I lose my momentum and have to wait for the rpm's to build before the car will accelerate.
Inspect and test all the following listed below:
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Manifold absolute pressure sensor.
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
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.
