Why does gsx always report idle cutting failure and how to solve it?

Does the subject want to ask "why does gsx always report idle valve failure and how to solve it?"

1. Clean or replace the gsx idle speed control valve.

2. Then use a special decoder to basically set the idle speed. Due to oil pollution and carbon deposition, the idle speed control valve is slow or stuck, and the throttle valve is poorly closed. Therefore, ecu can't adjust the engine idle speed correctly, which leads to unstable idle speed, so it always reports idle speed fault.
