What if BMW 1 Series 120i has a high idle speed?

BMW 1 Series 120i takes the lead in solving the problem of high idle speed as follows: 1. Block the damper with your palm. There will be two situations. The engine stalled. The engine does not stall;

2. If the engine is turned off, the air leakage is inside the throttle. If the engine is not turned off, the air leakage outside the air intake system needs further inspection. Now specifically, the throttle leaks;

3. Block the idle side exhaust hole of the throttle with your fingers. If the engine stalls, it is a control problem of idle motor system. If it is not closed, there is a gap in the throttle.

There is a gap in the throttle valve replica, which can be sealed with rubber. If there is a problem with the idle motor control system, you can use the oil-saving idle motor to solve the problem.
