How to clean the throttle of Mitsubishi pterosaur engine

Excuse me, is the engine idling unstable? Or where was it repaired? The normal idle speed of Mitsubishi Wingshen is very low, about 650 rpm. If it is difficult to start a cold car, the throttle is generally dirty. Wing Shen engines 1.8 and 2.0 are imported, which requires higher working conditions. Generally, the throttle valve is cleaned every 20,000 kilometers. If it is cleaned in a 4s shop, the technician will use a computer to re-match it. If it is self-cleaning, it is recommended to disconnect the negative battery for two minutes and then reconnect it. After turning on the switch, without starting the engine, turn the starting key to the second gear and stay for 15 seconds, and the engine computer will initiate re-matching, and then start the engine to idle for 15 minutes, then the car will have a problem. Ask the car master. 4s shop professional technician, 10 minutes to solve.
