Instructions: How to Fix a Stiff Gas Pedal

Step One:

When you want to fix a stiff gas pedal, the first step is to remove the gas pedal from your car. This can be done by opening up the driver-side door and popping off the cover on top of it that reads Pedal.

Remove The Gas Padel

Step Two:

Once you have removed this, use your Phillips head screwdriver to remove the bolts that attach the gas pedal to your car.

Step Three:

The next step is more difficult, so you need a knife and a small thin object to fix a stiff gas pedal. First, you want to cut open up the underside of your gas pedal with your blade, which will reveal some metal rods.

Step Four:

Spray some WD-40 into the rods and wait for five minutes. This will help release any metal particles that have built up inside them and lubricate them, so they are less stiff.

Step Five:

Reattach the gas pedal to your stiff gas pedal. Re-screw in the bolts you removed earlier and replace the cover.

Step Six:

You’re done! Test out your stiff gas pedal by driving it around, make sure everything is working properly before continuing.

Precautions To Take

  • Be sure to wear gloves.
  • Wash your hands after handling.
  • Remove any dirt and grime from the gas pedal with a cloth, then polish it dry as much as possible.
  • Wear a respirator mask if you want extra protection against fumes and dust particles.
  • When working on the gas pedal, disconnect the battery from the car so that there is no chance of accidentally shorting out anything while carrying out this repair project.
  • You can also cover up as much metal as you can with the plastic bag to prevent any chance of sparks.
  • Place the plastic bag over the gas pedal. If you really want to, you can place a towel underneath it for extra protection if needed.

Frequently Asked Questions

Q: What Causes the Accelerator to Be Stiff?

A: There are many potential reasons for the accelerator to be stiff, including a clogged vacuum hose or air intake boot. The problem could also stem from damaged wiring that would require an expert diagnosis. If you believe your vehicle has a faulty throttle position sensor (TPS), this will cause acceleration problems and make it difficult to accelerate smoothly because the computer isn’t receiving information about how much gas is being applied to the engine by way of pedal input.

Q: What Does It Mean When Your Car Pedal Sticks?

A: A sticking car brake usually indicates the brakes are being applied too hard or not enough for the time needed going up hills. Low/no pressure can also cause this in an anti-lock braking system (ABS), which will then prevent stopping power from applying evenly to all four wheels of the vehicle; alternatively, this may indicate that there is air trapped inside one of the ABS sensors and need replacing. Lastly, a stuck pedal may indicate that your clutch is being pressed too hard or not enough if you have a manual transmission.


Oftentimes, a gas pedal will become stiff due to dirt and grime. This can happen from accidentally spilling coffee on the floor mat or just not using your vehicle as often.
