What happens if the throttle is not cleaned?
2 Answers
The consequences of not cleaning the throttle are as follows: 1. It may cause errors in the throttle opening angle; 2. It may allow air with impurities to enter the engine combustion chamber; 3. It may lead to abnormal engine operation, mainly manifested as unstable idling, sudden throttle closing sensation while driving, reduced power, and in severe cases, even difficulty starting and increased fuel consumption. Methods for cleaning the throttle are as follows: 1. Throttle removal cleaning method: This task is relatively troublesome, so it is recommended to go to a repair shop for cleaning. 2. Non-removal throttle cleaning method: Directly spray throttle cleaner on a cloth and clean the throttle.
If the throttle body gets dirty and isn't cleaned, the car will drive terribly! I've experienced it myself - the car would shake like a sieve when starting, and the tachometer needle would dance up and down at red lights. Pressing the accelerator felt weak with delayed response, making overtaking particularly unconfident. The most annoying part was the fuel consumption skyrocketing - what used to be 500 km per tank dropped by 70-80 km when carbon built up. The exhaust smell became pungent too, stinking terribly when windows were opened. The mechanic said those oil sludge deposits were jamming the throttle plate, restricting airflow and affecting combustion efficiency. After reluctantly spending over 200 yuan to clean it, the engine immediately became quiet and smooth, with fuel consumption returning to normal. Now I clean it every 20,000 km - the car behaves perfectly.
