Recently, the idle speed of automobile engine is always unstable, and the throttle and idle motor have been cleaned, but the problem remains, and the car often has a meal during driving.
There are many reasons for engine jitter when idling. When the engine is idling, the on-board control system controls the opening of the idle valve through the signals fed back by various sensors. Therefore, if the engine idling jitter is serious, the first thing to look at is whether the idling speed is stable? If it is stable, it can focus on vibration reduction. If the idle speed is unstable, it can be roughly divided into two parts: 1. Is the feedback signal of each sensor normal? The quickest way to check this part is through Excelle's automatic detector. 2. The second part is the oil supply system. Are ignition systems such as spark plugs and high-voltage lines contaminated by oil leakage and working abnormally? Has the gasoline filter been replaced for a long time? Even the quality of gasoline is considered, because you have just cleaned the oil supply system, so this part is not considered. Does the valve cover gasket leak oil?
