Due to the impact with the environment and fuel quality injectors, intake manifold, intake and exhaust valves and the combustion chamber is easy to produce gelatinous precipitates, etc., affect the normal fuel supply, cause by fuel injection quantity control is not accurate, the fuel spray is bad, the oil pressure regulation failure, which causes the engine idle speed instability, the acceleration bad, knock, lack of fire, fuel consumption, exhaust emissions exceed the failure phenomenon. These faults can be using the Launch X-431 PAD or Launch X431 Creader VIII tool checked out.
