Hello, I'm Danny.
No, there is no need for you to replace the ignition coil. Only reason to do that is if vehicle wont start. For a basic tune-up just replace the spark plugs and possibly change the fluids if needed. I can attach a service schedule if needed if you don't have the factory Jeep owners manual. Hope this helps and thanks for using 2CarPros.
