Engine Idle Speed Is Unstable, Jitter, Oil And Flameout

1. Engine idle speed is unstable, jitter, oil and flameout

The main cause of this failure is that the idle motor and the idling channel are contaminated by carbon deposits. After the carbon deposition of the idle passage, the air flow is limited and the idle motor and throttle are constantly adjusted to maintain normal operation of the engine. On the one hand, the regulation function is limited due to carbon contamination of the idle motor and the throttle itself. On the other hand, as carbon pollution increases, the adjustment function of the idle system will reach a critical value and cannot be adjusted to generate revenue. Oil quenching phenomenon. At this point the ECU will consider an idle motor or throttle failure. In fact, this is due to carbon deposition in the idle system.

2. Power loss, poor acceleration

The main manifestation of this type of fault is that the engine responds slowly when accelerating and the response is delayed. When it is required to drive at full power, it feels insufficient power and feels unhappy.

Cold cars are hard to start. Surge, increased noise, excessive exhaust emissions

4. In order to prevent car carbon damage in advance, it is recommended to start decarbonization with hydrogen and oxygen after driving 20,000 kilometers, and then use hydrogen and oxygen decarburizer for carbon removal every 10,000 kilometers.
