1 Stuck or Sticking throtte plate
2 Poor electrical connection
3 Failed throttle control actuator

When I'm driving on the highway the car would lose all power to the gas pedal. The car engine would still run while this occurs. I would pull over on the shoulder and cut off the car about 1-2 minutes and restart it. The problem would occur about 3 times per day.

1986 Bronco II, 6 cylinder. Finding gas mixed in oil. Will start, but has problems running. Power isn't what it should be. Main problem is gas in the oil. Where could this be coming from.


from unburt fuel in the motor and exhaust. Completely sure thats it. had same problem. Make sure your engine is running hot and and normal operating tempurature. check over all your thermostate sensors. check to make sure actual thermostate is not stuck open. to much gas going through carburator. spark plug not getting efficent fire.
