Hi,
Cylinder one is at the front of the engine (where the accessory drive belt/serpentine belt) is located.
I attached the image below for you. If you have a cylinder one misfire and question if it is the coil, switch the coil with cylinder two and see if the misfire moves to cylinder two. If it does, then you know for sure the coil is the issue. If it stays on one there may be a different issue.
The suggestion is to confirm before purchasing a new one. Most parts stores won't take an electrical component back.
Let me know if this helps or if you have other questions.
Take care,
Joe
