Gas petal stickin in the truck?
Sounds like a butterfly valve issue. I found and included some info below, it was the method used for a car- but, you can vary the process for what works best with your truck-this should hopefully help you deal with the issue on a do-it-yourself basis...





Here's what you will need:





1)A can of Carburetor Cleaner


2)An old Toothbrush


3)Some Paper Towels


4)Phillips Screwdriver


5)Metallic Chewing Gum Wrapper


6)Titanium Bike Frame Pipe


7)A friend (or spouse) who’s willing to sit in the car with their foot on the gas pedal for about 5 minutes. (beer bribes work) LOL





If you can park your vehicle so that the passenger side is higher, than the the driver side, great! If not, no worries, you’re just going to make a lot of smoke. I’ll explain later. Turn the car off, open 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. When you press your gas pedal, this pulley turns, opening up the valve that lets air into the engine. This valve is what needs to be cleaned. To remove the hose, you’ll need to 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 Then, push a wad of paper towels under the opening.








This is the part where you need someone to get in the car and hold the gas pedal down. DO NOT start the car. You’ll notice that when they press the gas, the circular butterfly valve inside the throttle body will be open. With this valve open, you’ll want to attach the little plastic straw to your can of carburetor cleaner (which is about $3 at an auto parts store) and saturate the inside of the throttle body. Be sure to get the entire surface of the valve flap as well. This should loosen up some nice black gunk around where the valve usually touches the walls of the throttle body. 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. Now this is the fun part. Crank you engine and let the car/truck sit running for a few minutes. Depending on how much carburetor cleaner is still in your throttle body, your car exhaust will put off a nice steady flow of white smoke. I’m talking voluminous puffy white clouds. Dont worry it WILL go away, After about 5 or 6 minutes .





I sure hope this info helps! *singing everyone loves a pickup man*

Good luck!
Reply:very good answers here, It could be a motor mount issue also
Reply:What is it? Make, Model, I am not a mind reader. If the idle is fast, you may have an idle air control valve problem, or idle speed motor concern. This would cause a high idle problem on a modern vehicle. The Ford vehicles have a problem with sticking throttle plates as well. A throttle body replacement will solve this problem. This is characterized by a hard to push gas pedal, and then suddenly it breaks free and zoom you are off to the races. May be a sticking throttle plate.
Reply:My truck (GMC) had the same problem. The throttle body gummed up and was causing the pedal to stick. It was a quick fix. Take off the air intake duct, open up the air valve and their should be some gum causing the valve to stick. Apply some cleaner to the problem and you are good to go! It could also be your throttle cable either loose or possibly in a bind.
Reply:A: Replace the accelerator cable. Won't cost more than twenty bucks.


B: Maybe the problem isn't the cable...have you checked to make sure the throttle plate and linkages move freely and aren't sticking? Hose those down with some carb cleaner
Reply:you might end up replacing the cable
