Why do you want to clean the car throttle?

Hello, because the engine is running, a small amount of exhaust gas generated by combustion in the cylinder will generate carbon deposit at the throttle body through the intake valve and intake pipe. In addition, after the air passes through the air filter (especially the air filter that has been used for a long time), impurities will remain in the throttle. When these dirt accumulate, it will form dirt on the throttle body for a long time, which will lead to the increase of throttle opening and closing resistance, and the throttle closing will not reach the set standard value, resulting in engine idling instability, idling jitter and other faults, so the throttle should be cleaned regularly.

I hope this answer can help you, and I hope it will be adopted! ! !
