Should the vehicle clear the accelerator tachometer?

There are two kinds of throttle valves, namely cable type and electronic type. The cable throttle can be disassembled and cleaned directly with detergent. Professional maintenance method is to use special cleaning agent for cleaning and maintenance, and professional cleaning agent products can effectively solve the dirt (dust) on the throttle. The electronic throttle can't be cleaned at will, so it needs to be electronically equipped or disassembled, reset or directly sprayed for cleaning. If you don't have a computer after cleaning, the car will run off (the idle speed will rise and fall), you can't afford to refuel, and the exhaust gas will exceed the standard.

I hope it will help you, and I hope it will be adopted. Thank you!
