Maybe it is not a big problem.

Sorry there is no chinese input on this computer.

Start from the easiest, simplest things, like checking spark plugs, spark plug wires, ignition coils. If any of these parts has a problem, it will cause rough idling or riding, just like what you mentioned.

If the CHECK ENGINE indicator is solid on, you can read the code saved in the computer with a code reader or scanner. Post the code here, maybe someone can help you out.

One tip for checking spark plug wires. Start your car in a dark night, check if there are any sparks around the outside of wires. If so, you are a lucky guy, changing wires will fix it.
