Chevrolet mai Rui Bao xl535 jitter problem?

Reasons for the jitter problem of Chevrolet Mai Rui Bao xl535: 1, too much fouling on the throttle valve and air intake will lead to the change of the cross-sectional area of the air passage, which will make the control unit unable to accurately control the idle intake air, resulting in the mixture being too rich or too thin, resulting in abnormal combustion and jitter; 2. The spark plugs caused by individual spark plug failures are too weak, which will affect the performance of the car, leading to the symptoms of "fire" and unstable idle speed; 3. Fuel pressure is faulty. If the oil pressure is too low, the fuel sprayed by the injector will be in a bad atomization state, or the sprayed fuel will be linear. In severe cases, only oil droplets will be sprayed, and the reduction of fuel injection will make the mixture too thin, which will happen.
