When Camry starts, turn on the air conditioner and turn off the air conditioner. What's with the trembling?

1. When the air conditioner is turned on, the engine shakes, the idle speed is too small or the engine is turned off. It is recommended to check whether the engine throttle needs cleaning. If the throttle and idle motor are dirty, it will affect the idle intake, especially when the air conditioner is turned on.

Second, if there is too much sludge in the throttle valve, it may cause poor engine acceleration and increase fuel consumption. You can simply clean it, or you can go to a 4S shop and ask a professional to clean it.

Third, the cleaning method:

1. Apply some oil to the fixed metal beam ring first, so as to avoid slipping teeth during disassembly;

2. Remove the metal ring of the throttle hose. After the hose is removed, the left end is the position of the throttle. Remove the negative battery, turn off the ignition switch and straighten the throttle.

3. Spray a small amount of carburetor cleaner into the throttle, and then scrub it carefully with polyester rag or non-woven fabric. Deep in the throttle, where you can't reach it, you can clean it carefully with a rag.
