Performance failure of Buick LaCrosse active shock absorber

The throttle is too dirty. Just clean it. Throttle is a controllable valve that controls air to enter the engine. After air enters the intake pipe, it will be mixed with gasoline to form combustible mixture, thus forming combustion work. It is connected to the air cleaner at the top and to the engine block at the bottom.

The reason of throttle scaling mainly comes from oil vapor, followed by particles and moisture in the air, that is to say, using qualified air filters and removing crankcase ventilation pipes will make the throttle sewage discharge speed much slower.

Too much sludge in the throttle may lead to poor engine acceleration. If cleaning is needed, the throttle can be cleaned without disassembly, but the sealed part of the air inlet must be cleaned, and the idling motor must be removed before cleaning.

After cleaning, follow the disassembly procedure just now, and then start the initialization of the throttle valve after installation. After cleaning the throttle valve.

Initialization is necessary because when the computer adjusts the throttle opening, it has a memory function. Because there was sludge blockage in the past, in order to ensure air intake, the computer will automatically adjust the throttle opening to make the air intake in a normal state.
