Qichen d60 turns on the air conditioner and the engine shakes.

There are many reasons why the air-conditioning engine shakes when the car starts, including air-conditioning compressor failure, throttle blockage, engine carbon deposition, spark plug failure and so on.

1. Air-conditioning compressor failure: If the air-conditioning compressor fails, the pressure will be too high, which will cause the air conditioner to shake when in use, which will further affect the engine and lead to engine vibration. There are many reasons for the failure of air conditioning compressor. In this case, you need to go to a repair shop or a 4s shop to ask a professional to check and maintain it.

2. Throttle blockage: If the throttle is blocked, it will affect the intake function of the engine, resulting in poor ventilation of the engine and abnormal vibration. This situation requires checking and cleaning the throttle.

3. Engine carbon deposit: Serious engine carbon deposit is the main reason for engine jitter. If the engine carbon deposit is not effectively cleaned, it will affect the normal combustion of fuel and lead to abnormal engine jitter. In this case, it is necessary to clean up the engine carbon deposit in time.

4. Spark plug failure: When the spark plug is seriously worn, the fuel of the engine will not ignite normally, resulting in engine jitter. In this case, a new spark plug should be replaced.
