Do I need to start the engine when cleaning the engine valve?

Specific process:

First, unplug the car key, open the hood and find the throttle of the engine.

Remove the air filter and intake pipe with a screwdriver, and unplug the electric socket on the throttle; Then unscrew the three hexagon screws on the throttle with a hexagon screwdriver (pay attention to this step, and be careful that the screws are "lost"). Guangdong Easy Car Service Bian Xiao said that after removing the screws, you can take out the throttle and then plug the air inlet of the engine with a dry rag to prevent dirt from entering the engine.

First look at whether the removed throttle is black, and then spray detergent, and the dirt will slowly dissolve. At this time, you can wipe it with a paper towel and spray detergent again, and the throttle will become clean and beautiful. After that, you don't need to wipe it with a paper towel, so that the residual detergent can be left on it.

The rest of the process is simple, and the disassembly sequence is reversed and reset one by one; Finally, turn the key to the ignition position (do not start) and turn it off after 5 seconds. This is an "initialization" process.
