The idle speed of the car is unstable after cleaning the throttle.

It is likely that after cleaning the throttle, I forgot to use the tester to learn the idle speed again. \x0d\ Because Cruze uses an electronic throttle, the idle speed control of the vehicle using the electronic throttle controls the idle speed by controlling the opening of the throttle, which is different from the cable throttle used before. The cable throttle controls the idle speed through the idle motor. \x0d\ Moreover, whether the cleaning throttle is manually opened for cleaning will affect the opening of the computer-controlled throttle when idling. Therefore, there will be a low-speed unstable fault phenomenon. \x0d\ It is recommended to relearn the opening with the throttle valve.
