You should have also have had a code for misfire. 3001 - 3006?
Welcome! There should be some good videos on testing the coil pack.

No sir
Try this. Pull your battery cables for about 30 seconds and tough them together. This will set the ECM. The computer may need to reset itself. Beware these Jeep computers are kink of stupid and slow to learn
