How to solve the problem of CRV shaking when the air conditioner is on but not when it's off?

[FaithFitz]

Here is information about the CRV shaking when the air conditioner is on. Excessive carbon deposits: If the engine's throttle has not been maintained for a long time, it is easy to accumulate carbon deposits. These deposits can obstruct the engine's intake system, leading to incomplete air intake. As a result, the engine may struggle or barely manage to drive the compressor, causing idle shaking. Damaged spark plugs: Check the condition of the spark plugs, high-voltage wires, and ignition coils. Spark plugs are parts that are prone to wear and tear. Poor spark plug performance can cause the engine to shake during startup, affecting the engine's power output. Combined with the additional load from the compressor, this can lead to shaking when the air conditioner is on. If the spark plugs have excessive carbon deposits or are damaged, it is recommended to replace them directly.
