What are the reasons for the EPC light on and insufficient power in the Shuailing?

[JosephLynn]

Here are the specific reasons for the EPC light on and insufficient power in the Shuailing: 1. Intake system failure: such as leakage or blockage. Troubleshoot the intake system, use qualified fuel, clean the throttle body, etc. 2. Dirty throttle body: or excessive carbon deposits, clean the carbon deposits in related parts. 3. ECU failure: reprogram the ECU-related data, use this method when other faults cannot be eliminated after troubleshooting. 4. Engine management system failure: this situation is often accompanied by unstable vehicle idle speed and engine cold start shaking. Most of the time, it is due to the poor quality of domestic fuel and dirty driving environment. In such cases, the vehicle should be immediately taken to a repair shop for inspection and repair.
