In 2003, what should I do if the throttle nozzle is unstable after Fukang cleaning?

As for your question, since you haven't seen the existing car, if the reason is that the engine is shaking when stopping after driving, it may be caused by too much carbon deposition in the throttle, nozzle, intake valve, combustion chamber and intake pipe. Therefore, you can't just clean the throttle and nozzle, because these carbon deposits will block the idle channel, make the idle motor jam or exceed its adjustment range, and lead to low idle speed, unstable idle speed, oil collection and flameout. Also pay attention to check whether the solenoid valve of the carbon canister is out of order, which leads to the phenomenon that the mixture is always very thick when the engine is working, resulting in jitter when driving at low speed.

I suggest you go to a 4s shop or a repair shop to check whether the parts analyzed above are faulty.
