Cleaning method of Buick lacrosse throttle

If there is too much sludge in the accelerator, it may cause poor engine acceleration and increase fuel consumption, which is a big worry for the owner. What should I do if the throttle is dirty? Just clean it up, and you can do it yourself, just don't forget to initialize it.

First, apply a little oil on the fixed metal beam ring to avoid slipping teeth 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 electrode of the battery and 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 hold the rag and scrub it carefully where your hands 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. Nozzle borrowing cleaning and disassembly-free cleaning have their own advantages and disadvantages. Under normal circumstances, the maintenance station recommends no disassembly and cleaning.

Prevent other unnecessary waste, such as the need to replace the sealing ring or install other gaskets after disassembly, or the oil leakage and air leakage during disassembly and assembly, which will delay the owner's time.

After cleaning, the throttle valve will be initialized after installation according to the disassembly procedure. 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.
