What are the symptoms of a faulty car compressor solenoid valve?

[DeEsther]

The following are the possible conditions when a car solenoid valve fails: 1. The engine idle speed fluctuates and becomes unstable, with poor acceleration; 2. Gear shifting may cause jerking; 3. The engine is prone to stalling or difficult to start; 4. Turning on the air conditioning may result in stalling or other malfunctions. The car solenoid valve is an actuator in the electronic control system. The carbon canister solenoid valve is a device installed in cars or motorcycles to reduce pollution caused by fuel evaporation emissions and simultaneously improve fuel efficiency. When the engine is off, the vehicle's activated carbon canister begins absorbing fuel vapors evaporating from the fuel tank, locking them firmly within the micropores of the activated carbon in the canister to prevent the vapors from escaping into the atmosphere. When the engine starts, the absorbed fuel vapors in the carbon canister are delivered to the engine as fuel.
