Hi, first of all, take your car to any auto zone place or mechanic and they can check your computer for trouble codes to see why it isn't accelerating. It sounds to me like something is wrong with your Throttle Position Sensor, it tells the computer how far your pushing down the throttle to allow the proper ammount of fuel to be injected into the engine, it may have a bad spot in the sensor so when you push the throttle down that far, it's malfunctioning and the computer doesn't know to inject more fuel into the engine to accelerate faster. When this sensor fails, it won't accelerate fast enough and then it should normally store a trouble code in the car CPU....

The relay is located in the Fuse/Relay box as shown. You may find that your fuel pump is not putting out the required pressure though.

I would change the transmission filter and fluid first. It could be that your filter is old and stopping the transmission from working properly.

If a transmission fluid and filter change does not solve the problem, then it's time for a transmission rebuild or replacement. This can often happen if the car was driven improperly, such as sudden stops and starts, jamming the clutch into gear (in manuals), down shifting while the car is in another gear or from old age.

My 1998 ford ranger 2x2 has shown to accelerate upon braking


This sounds like your rear brakes are out of adjustment and the brake peddle has too much travel. On a sudden fast stop both the brake an gas peddle get stepped on. Had this prob with a car last week. Frankster016
