when im on the highway driving for 30 minutes to an hour, the throttle feels like it just goes dead for a few seconds. Eventually after 5-10 seconds it kicks back on and the truck jerks and starts driving normal. It can happen a minute later or 15 minutes later but it normally lasts for just 5-10 seconds. It has happened getting off the highway when starting to accelerate after a stoplight and the truck wheels stopped and the truck didnt stall so i cant imagine its spark or fuel issue. it never has really happened on short drives or even idling for long periods of time. It doesnt happen around town. Only constant speed and throttle use. Please help. ---

The throttle position sensor may be faulty. ![image](https://global.discourse-cdn.com/cartalk/original/3X/e/1/e1db6e3fc86987df60206af6c8afd6470b21636d.jpeg) This is mounted on the throttle body, and informs the computer the position of the throttle so the computer knows how much fuel and ignition is needed to allow the vehicle to accelerate. Sometimes these sensors can be effected by heat as they get old. Tester ---

thank you for your answer. This is what I originally thought but when the throttle cuts out, I tried to “pump” the throttle and it wouldn’t kick over right away. I feel like if it was a TPS, the throttle would “wake up” once the position is changed. What do you think? A MAP sensor caught my mind too ---

If you were driving an 87 Tempo I would say to change the O2 sensor. 2.3 L. That used to happen at steady speeds. ---

I do have a manifold leak before the o2. Possibly the o2 is reading too much air? ---

Hopefully, George will log in to help, as he is very knowledgeable about 30+ year old Ford trucks. ---

Just to confirm, the throttle pedal goes dead and the engine RPMS drop with no response to pressing the accelerator pedal?? Or does the vehicle go into a false neutral and the engine RPMS go up?? ---

Just a thought, when was the last time you changed the fuel filter? [Fuel Filter Replacement / 1993 F150](https://www.youtube.com/watch?v=ZNvr1Em6tsU)
