How to solve the throttle fault

Solution to the throttle fault: 1, whether the acceleration of the car is flexible or not has a great relationship with the dirt of the throttle. Cleaning the throttle can reduce fuel consumption and make the engine flexible and energetic; 2. The main symptoms of automobile throttle damage are engine jitter and unstable idle speed, because the throttle is a vulnerable part and needs to be replaced frequently. As long as the above situation occurs, after other possible faults are eliminated, the throttle sensor is faulty and should be replaced in time; 3. In other words, the throttle is dirty and the vehicle is idling; Cold cars don't strike easily; The indication of tachometer is unstable at idle speed (unstable at idle speed); 4. The composition of electric throttle can be roughly divided into the following parts: throttle, electromagnetic driver, potentiometer, controller (some are not directly managed by ecu) and bypass valve. Its fault characteristics are divided into two categories: hard fault and soft fault. Hard fault refers to mechanical damage, and soft fault refers to dirt, maladjustment, etc.
