There's air in the car compressor. Will the engine tremble?
This will not affect the vibration of the engine, will only affect the cooling effect of air-conditioning.
Hello, won't tremble, check the spark plug or ignition coil
First, the possible cause of the failure(I) intake system.Intake system is an important part of electronically controlled fuel injection system. The main causes of air supply failures are:1 、 intake manifold and all kinds of valve leakage, common intake manifold failure, air intake manifold seal is bad, vacuum tube fall off, PCV valve, /EGR valve closed lax. For example, under normal circumstances, the opening of idle speed control and intake should be strictly followed by a certain function, that is, idle valve is opened, the intake will increase. When the air supply system is leaking, the intake amount and the idle control valve opening can not follow the original function, and air flow meter can not accurately measure the real cause, engine electronic control unit (ECU) to obtain the signal near the gas caused by misjudgment, the engine idle speed instability.2, idle air channel and lead to excessive solar term door fouling, air inlet cross-sectional area changes, as well as the misalignment of the idle air control, so that the amount of air entering the cylinder is deviated from the normal value, causing the mixture too thick or too thin, the combustion is not normal, causing the engine idle speed instability.3 、 sensors and other circuits that control idle speed are out of order. If the idle switch can not be closed, ECU error determination engine at part load, the inlet air flow control error; idle valve due to oil, carbon and action lag or card, solar term door is not tightly closed will cause the idle ECU cannot adjust the engine on the right, the other air inlet temperature sensor, air flow sensor, water temperature the sensor and sensor circuit, circuit breaker will cause the engine idle speed instability.
