I cleaned the throttle and nozzle of a century rookie, and then the car stopped. Please give me some advice.

If the computer tests are normal, the problem is mechanical failure. Did you use a nozzle tester to test whether the nozzle works normally after cleaning? It is very likely that the fuel nozzle was cleaned, but the carbon deposit got stuck in the fuel path or the fuel injection hole of the fuel nozzle, which led to no fuel injection and no atomization, and the car could not be hit.
