Code reader says no 4 cylinder is misfireing they said it means plug wire or no 4 plug

No wires on your car,it has 4 COP's (it has ignition coils,one over each spark plug. it's possible that #4 COP is failing. you don't need to drive it with the CEL blinking/flashing. also,you could clear the code,swap #4 cop with #3 cop and see if the misfirecode follows the #4 coil,if it does show a misfire on #3,then you will know it's the coil that's failing and needs replaced.Local auto parts stores are a rip off on parts @ $75.99 ea coil for Delphi Part Number: GN10330(over $300.00 for 4 coils). rockauto.com, same exact part # are $28.79 ea! you can get all 4 for $115.16 plus $7.89 2-3 shipping, total $123.05,no sales tax,and might as well order 4 spark plugs also. you need to do this anyways if they haven't been changed or if it's been a long time since. copy and paste DIY video link below. also there is a link for rockauto.com,copy and paste it also. https://www.youtube.com/watch?v=qRvV3cAPy30 https://www.rockauto.com/en/catalog/kia,2008,rio5,1.6l+l4,1441824,ignition,spark+plug,7212
