Just after washing the throttle, the old fox began to idle and shake for help.

I don't know where you do the maintenance. Did you open it and wash it?

If you don't unpack and wash the bottle, that method is more deceptive. For a dirty throttle, it can't be cleaned. It may be that carbon deposits and oil stains adhere evenly along the edge of the throttle blade, but they are uneven after washing the bottle, which leads to poor opening and closing of the throttle, and the result is obvious idle jitter.

If it is disassembled and washed, it will be cleaner after cleaning, but it needs to be re-matched. I have used two matching methods, one is to match the instrument with the computer, and the other is not to start the engine after installation and step on the throttle for a long time to reset the throttle. Either way will do.

I don't know what kind of situation you are, but the most likely reason for idling jitter is that the throttle opening and closing are not smooth. Go to the cleaned place and check and adjust again.

The answer suggestion comes from the TS DM team.
