An engine performance diagnostic test needs to be performed. Spark plugs, ignition components such as wires and coils can be at fault. The vehicle also could have a vacuum leak causing idle difficulties. Many possibilities exist as to the source of your issue, so only a qualified technician performing a diagnosis will be able to give you a clear picture of what's going on. Good luck.
