Who knows how to clean the throttle of Volvo s80?

Personally, I think the most effective way to clean the throttle is to disassemble and clean it. The first layer should clean the nozzle and oil passage. You can also clean the throttle yourself. Firstly, the air filter part (including air filter shell and pipeline) is removed, and the exposed metal part (aluminum) is the throttle valve; Then unplug the oxygen sensor (near the accelerator), and be careful not to break the wire connecting the pins when unplugging; Finally, remove the four fixing screws and the throttle will be taken off. Clean with carburetor cleaner.

But generally speaking, if the throttle valve returns to normal, the main reason for high fuel consumption is that the nozzle is too dirty, which causes poor atomization of gasoline and affects the combustion effect; The spark plug has not been replaced for a long time, and the ignition effect is not good, resulting in insufficient combustion; Low tire pressure will lead to increased rolling resistance. Many reasons. I hope you can judge the reason for the increase in vehicle fuel consumption according to your actual situation. Finally, I'll give you a trick to clean the throttle in Volvo s80 4S store. Once you look at it from the side, you will understand everything.
