It is likely that your spark plugs and/or ignition coils need to be replaced. I suggest taking your car to a mechanic to have them checked.

Your air filter may be clogged, causing a decrease in engine performance. Try replacing it with a new one.

Have you checked your fuel pump and fuel filter? These components could be the culprit of your rough idle.
