While I was driving my car on a 35 mph road my car stopped accelerating when I pressed the gas pedal and instead began to rev the engine. If I coasted for about 50 yards and pressed the pedal (at 25 mph) I was able to continue keeping my car at the correct speed but I couldn't keep pressure on the gas pedal for long. About two miles down the road my car would only tolerate slower and slower accelerating speeds.

try by replacing the spark plugs and the plug wires and add some injector cleaner to the fuel tank

have your spark plugs, coil pack boots checked for moisture,on many ford water will accumulate around plugs,expeually if it has rained recently.

I have the same car. So far no problems with the Transmision. I had the Trans oil change out every 60 K
Sure sounds like you need to get the Transmision checked. Is the fault light on. I have invested ina fault code reader sure is worth it.
Good luck. Vilmos

Check your TPS Throttle positioning sensor. Sounds like it has a dead spot in it or it is failing. May also be a wiring harness issue or loose connection at TPS too! If its intermittent then it will soon go out completely. It should be located on your fuel pedal. Remove it and check it with an ohm meter. Check resistance all the way thru from 0-100 percent. When it is not working it should do nothing and show no resistance. When it is working the resistance value will increase and or decrease as you turn the sensor.

You sould have recieved a "recall" notice in the mail about the cruise control for fire and failure issues. they are adding a fusable link where the cruise control harness connects to the brake master cylinder. if you have not had the recall performed yet you should SERIOUSLY consider getting it done, mainly so it doesnt catch fire, but "could" be the result of the failure you've been experiancing! btw, almost ALL Ford vehicles have been affected with the cruise control recall. hope this helps!
1. Start the engine when the engine coolant
temperature gauge needle points to C. Allow
the engine to idle until the gauge needle
points between the C and H (normal operating
temperature).
2. Accelerate the vehicle to 55 MPH (88
km/h), then quickly release the accelerator
pedal completely and keep it released for at
least 6 seconds.
3. Quickly depress the accelerator pedal for a
moment, then drive the vehicle at a speed
of 53 to 60 MPH (86 to 96 km/h) for at least
5 minutes.
4. Stop the vehicle.
5. Accelerate the vehicle to 35 MPH (55 km/h)
and maintain the speed for 20 seconds.
6. Repeat steps 4 through 5 at least 3 times.
7. Accelerate the vehicle to 55 MPH (88 km/h)
and maintain the speed for at least 3 minutes.
8. Stop the vehicle and turn the engine off.
9. Repeat steps 1 through 8 at least one more
time.
If step 1 through 7 is interrupted, repeat the
preceding step. Any safe driving mode is acceptable
between steps. Do not stop the engine
until step 7 is completed. If you cannot or
do not want to perform the driving pattern, a
NISSAN dealer can conduct it for you.
