My car is a carnival, how can I clean the accelerator myself?

Carnival is a little troublesome! First, pull out the key, open the water tank cover (the cold car may not open), remove the water pipe and screw on the throttle valve, take out the throttle valve, and clean it as you like with a toothbrush. I suggest you take photos with your mobile phone before disassembling it, and you can also look at the photos of your mobile phone when installing it.

Cleaning agent: Use a better throttle cleaning agent.

Without initialization, as long as you don't open the key, it won't have any influence.
