Gas pedal hard to push down or sticking

Cause of Sticking Pedal

When I press the accelerator or gas pedal, the initial touch requires a some force, were I almost have to stomp on the gas pedal to get it to go. So on my garage I try spraying some WD40 on the accelerator wire and spring that was exposed thinking it was just friction issue. But nothings happens.

It ended up for me to hit the search engine for the possible solutions and found a very simple one. The problem was the butterfly valve that allows air into the engine is getting stuck with carbon deposits. To deal with this problem you will need the following;

• Carburetor Cleaner
• An old Toothbrush
• Some Paper Towels
• Phillips Screwdriver

Start cleaning by opening up the hood, and look for the large black flex pipe that runs from your air filter to the top of the engine. There should be a metal wire on a pulley near where this pipe connects. To remove the hose, loosen up the hose clamp with the screwdriver. Once the clamp is loose enough to move around, pull the pipe off of the throttle body and push it to the side like the picture below. Then, push a wad of paper towels under the opening.

Use your toothbrush to scrub the walls and the flap as thoroughly as possible. If you can still feel grit around the edges of the flap, or the groove where the valve touches the walls, keep scrubbing and squirting carburetor cleaner as needed.

When you’re done scrubbing, wipe up as much of the carburetor cleaner as you can. Push the black hose back on to the throttle body, and tighten the hose clamp.

The acceleration on the Camry has never been smoother. Instead of having to stomp on the gas, it responds appropriately to the lightest touch.
