Troubleshooting the intake system, using qualified fuel, cleaning the throttle body, etc. Using unqualified fuel, abnormal cylinder pressure, poor working conditions. Remove carbon deposits from related parts and clean them. If the throttle is dirty, it should be cleaned. If the brake light is not working, check the brake switch and wiring. Re-flash the ECU-related data (this is done when other faults have been resolved but the issue persists). The possibility of other faults cannot be ruled out. The actual vehicle inspection results should be used as the basis for further repairs.
