How to Solve Throttle Sticking?
2 Answers
Throttle sticking may be caused by the throttle opening screw being too tight or insufficient lubrication of internal components. You can first adjust the throttle opening screw, then add some engine oil to lubricate the throttle spring and internal parts. The engine throttle is a crucial component in modern fuel-injected engine systems. The upper part connects to the air filter, while the lower part links to the engine cylinder block, serving as the throat of the automobile engine. The responsiveness of vehicle acceleration is closely related to the cleanliness of the throttle. To ensure the throttle can open and close normally, it should be inspected promptly. A good method to detect throttle issues is to press the accelerator pedal and observe whether the throttle can stand upright. If any problems are found, it's essential to visit a 4S shop for repairs immediately.
I usually enjoy DIY car repairs. Throttle body sticking is mostly caused by excessive carbon deposits. Over time, dust accumulation makes the valve stick, resulting in unstable idle speed or weak acceleration when driving. The solution is to clean the throttle body—first buy a dedicated throttle body cleaner, gently remove the intake pipe, spray the cleaner on the valve, and wipe off the dirt with a soft cloth. Be gentle to avoid damaging the components. After reassembly, remember to start the car and let it idle for a few minutes to adapt. Prevention is simple—check and clean it when changing the oil, or use higher-grade gasoline to reduce carbon buildup. In short, this small task isn’t difficult, but if not addressed in time, fuel consumption will increase, driving will become uncomfortable, and in more severe cases, it may lead to stalling risks.
