SPUTTERING, BACKFIRING.

1994 Ford Crown Victoria

Engine Performance problem
1994 Ford Crown Victoria V8 Two Wheel Drive Automatic 157000 miles

My crown vic starts fine--even on cold days. It idles fine. But when I press the gas (even in park) it starts sputtering and even sometimes backfiring. If I place it in drive and try to accelerate, the car just barely wants to move and the engine sputters and sounds like it is either starving or choking or such. If I let off the accelerator, runs fine.

I've checked all fluids and the air filter. Where else should I begin checking? I am not sure if this could be a fuel problem or something else. Thanks.

I upgraded to a bid question, and the money has been taken from Paypal, but it doesn't show in this forum. Please help! Thank you.

What is the engine type?

Symptoms described could be due to any of the following: 1. Throttle Position Sensor.
2. Mass Air Flow sensor
3. Fuel pressurre
4. Spark plugs, cables, ignition coils and distributor cap.
