How much is it for Corolla to clean the throttle?

The prices of 4S shops in different places are not uniform. General auto parts city or beauty salon use disassembly-free cleaning, plus a bottle of liquid medicine. The price is cheap, but the effect is very limited. It's best to go to the 4S shop to remove the throttle valve and clean it, so as to completely remove the carbon deposit on the upper and lower parts of the throttle valve. The price is more expensive, the working hours may be 240, and the cleaning liquid is more than 70. If the car does not shake at idle speed, or the acceleration is weak, it is not good for the car.
