Does the idle valve need cleaning?

Yes, when cleaning, remove the throttle valve first, and then remove the idle speed control valve. Idle speed control valve can be sprayed with cleaning agent on the cloth and then wiped clean. Diagnosis: Check the starting sound of idle speed control valve. If there is no starting sound, the idle speed control valve will fail. Troubleshooting: clean or replace the idle speed control valve, and set the idle speed with a special MA removal tool. Of course, the idle speed control valve is installed on the exhaust hole next to the throttle. According to the ignition signal, the idle speed controller will make the idle speed control valve act in time when the engine speed is lower than 750 rpm, so as to increase the engine speed. When the engine speed exceeds 1050 rpm, it will stop. In vehicles equipped with air conditioning system, this control valve is also called idle acceleration valve. After the air-conditioning compressor runs, the engine load is generated, which reduces the engine idle speed, and the idle speed control valve acts accordingly to keep the idle speed stable. Idle valve needs cleaning, and the cleaning method is as follows: 1. Remove the gasket from the regulating valve and clean the valve groove with cleaning agent; 2. Note that the control valve cannot be soaked in cleaning agent, gasket, shell, etc. Unable to clean; 3. Plastic knives can be used to remove places that are difficult to clean, such as valve cores, but hard objects such as screwdrivers and steel saw blades are not allowed; 4. If necessary, the valve seat must also be cleaned.
