A Sticky Problem: Chevrolet Silverado 2500HD Sticky Gas Pedal
In 2001, the Chevrolet Silverado 2500HD made its debut in the automotive market. The Silverado 2500HD is a significantly beefed-up version of the Silverado 1500. It defies the limits of strength, power and suspension. For each model year, Chevrolet continues to boost the Silverado 2500HD\'s heavy-duty capabilities and performance. Issues such as a sticky gas pedal is a downer in the Silverado 2500HD\'s continued popularity. If you have a sticky gas pedal problem in your Silverado 2500HD, fixing it shouldn\'t be a sticky situation. Here are three ways to solve this nuisance:
Adjust the accelerator cable
A likely cause for a sticky gas pedal or a sluggish throttle response in your Silverado 2500HD is a slackened or stretched accelerator cable. To fix this problem, you need to adjust the accelerator cable. The good thing is, you can do this yourself in just a short time and with only a socket set and driver.
Open the hood of your Silverado 2500HD and be sure to disconnect the negative cable from the battery before tinkering with any part of the fuel system. Using a socket driver, remove the retaining screw from the intake manifold cover. Then, remove the intake manifold cover and find the throttle lever and throttle cable assembly directly below where the intake manifold was.in the center of the engine.
The accelerator cable runs from the center of the engine to the accelerator pedal inside the car. Connecting the cable to the linkage is a black plastic nut which you should turn by hand in a clockwise direction. You will feel the cable tighten when you do this. Stop turning the plastic nut when the cable starts to become taut. Return the intake manifold cover and retaining screw. Return the battery cable as well to the negative terminal. Start the engine and see if it idles at normal speed. If it doesn\'t, turn it off and adjust the plastic nut on the cable back until the engine idles at normal speed.
Check and clean the throttle body
Another possible reason why your gas pedal gets stuck is carbon deposits in the throttle body bore and on the throttle plate. So, check the throttle body and clean it thoroughly if needed using a rag and a carburetor choke and throttle body cleaner. This should solve your gas pedal issue.
Inspect the inside of the throttle body for grooves too. The butterfly valve inside the throttle body has a propensity to deteriorate and settle into a groove that is created. In such case, replacement is recommended, although in some cases making adjustments with the set screw can fix it.
Lube the gas pedal pivot point
First, check if the gas pedal is getting lodged under the floor mat of your Silverado 2500HD. If your pickup truck has an adjustable pedal, raise it towards you and inspect if it still hits the floor mat. In addition, you may have to lubricate the pivot points of the gas pedal using a spray lube such as a dry graphite spray.
