1990 Ford Ranger Question: Engine speed increases when shifting

 

Question

Sometimes when I shift gears in my Ranger, the engine speed will increase after I depress the clutch and remove my foot from the gas pedal. After I drive it a while, the problem will go away if I turn off the engine for a couple minutes and then restart it. My mechanic is mystified. What could cause this?

    Did your mechanic figure out what was causing the surging problem?

    The fuel pressure regulator is faulty. If left unfixed gasoline will end up sucked into the brake booster wrecking it too.

    i had a problem like this, my truck would rev when in the clutch was pressed in, it drove me crazy, but i figured it out, i but seafoam in the gas tank, and it never happened again, my guess is i might have had water in the gas tank, seafoam removes water from fuel systems, great product, give that a try
