Why does the accelerator pedal of Chery QQ feel heavy?
2 Answers
Chery QQ's accelerator pedal feeling heavy may be caused by the spring under the pedal being too stiff, resulting in excessive elasticity. You can try using pliers to bend the end of the spring that hooks onto the pedal in the opposite direction to reduce its elasticity. If this is confirmed to be the issue, you can remove the spring, heat it until red-hot, and let it cool naturally to anneal it, which can also reduce its elasticity. Chery QQ is a model under Chery Automobile Co., Ltd., with body dimensions of 3564mm in length, 1620mm in width, and 1527mm in height, and a wheelbase of 2340mm. In terms of appearance, the Chery QQ's headlights resemble two cheerful big eyes, and the front grille looks like a small mouth.
I had the same issue with my brother's Chery QQ before - the gas pedal felt super stiff, like stepping on glue. Turned out there was a layer of sludge built up on the throttle valve. This happens to all cars over time, especially with frequent city traffic jams that cause more carbon deposits. Just disconnect the intake pipe, spray some carburetor cleaner, and wipe the valve gaps with a cloth - you'll immediately feel the pedal become more responsive. For electronic throttle cars, remember to reset the throttle body afterward; just visit a repair shop for an ECU recalibration. Always refuel at reputable gas stations - cleaner fuel with fewer impurities prevents clogging. A DIY cleaning on weekends takes about 30 minutes and saves you hundreds compared to shop service.
