After the car is started, the car body shakes seriously and sometimes turns off. Is it because the throttle is dirty?

The solution is: firstly, apply a little oil on the fixed metal beam ring to avoid tooth slipping during disassembly. Remove the metal wire harness 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, straighten the throttle plate, spray a small amount of "carburetor cleaner" into the throttle, and then carefully scrub it with polyester rag or high-spin "non-woven fabric". Deep in the throttle, you can clamp the rag and scrub it carefully where you can't reach it.

When cleaning the throttle valve, it is not necessary to disassemble it, but the sealing part of the inlet steam must be cleaned, and the idle motor must be disassembled for cleaning. There are advantages and disadvantages of cleaning nozzles by borrowing and disassembling. Generally speaking, the maintenance station suggests disassembling and washing, which can prevent other unnecessary waste, such as replacing the sealing ring after disassembling or installing other gaskets, or delaying the owner's time because of oil and gas leakage when disassembling.

After cleaning, the throttle will be initialized according to the disassembly procedure just now. After cleaning the throttle, it needs to be initialized, because the computer has a memory function when adjusting the throttle opening, because there was sludge blockage in the past. In order to ensure the air intake, the computer will automatically adjust the throttle opening to make the air intake in a normal state.
