try changing your fuel filter. It may be a throttle position sensor, but if it was an electrical problem, your "check engine" light would be on and a mechanic would have to put the computer on it to test.
I would suggest changing your fuel filter.

That code is for the Evaporative Emissions. It could be a bad Evaporative Emissions Canister Valve or just a bad vacuum line or my granddaughter's 1997 Ford Escort had that code and her gas cap was NOT on. Now when you figure out what one it is disconnect the battery for 10 minutes to reset the computer.

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.
