If you have coils and spark plugs then you don't have wires. From personal experience these car's misfire because of coils and BAD INJECTORS. If you replaces coils and sparks plugs you need to check injectors. Get a NOID light and check injectors pulse to make sure it good. First you must locate the cylinder that has the misfire/Missing,this can be done by using a computer/code scanner or if can be manually by disconnecting each coil and see when there is NO change in idling or shaking. What you are looking for is when you disconnect the Eugine should shake more and when you reconnect it would smooth en out. If any cylinder when disconnected the engine doesn't change that the one with the problem. Check again for spark and make sure it good. Then check that injector pulse plug off injector connector and connect it to NOID light you should get a constant flickering of NOID LIGHT. If you do then BINGO that injector is BAD. However I must say this test is on valued if you have performed a compression test on all cylinders to make sure there are no BAD/Burnted valves. This can be done with a compression guage remember the reading should NOT be more than 10PSI difference between all cylinders example of a normal reading is cylinder 1 170 psi cylinder 2 168 cylinder 3 172..... abnormal is cylinder 1 170 cylinder 2 85 cylinder 3 172 ...etc. I know this is alot of info but read through and follow these step and you'll be ASE certified by the end of this job. Good luck and thanks for using FIX YA
