I have a 2003 Deville with the DTC P1360 Ignition Coil Group 2 Control Circuit as well as another misfiring code ( I can't recall at the moment). I changed the Spark Plugs which has made a remarkable difference. The engine light has turned off after changing those, but orginally it pulled up the P1360 code. I am trying to locate the position of the cylinder 2. So I know which coil pack to replace.. is it the front bank or the rear bank.. and also what the exact firing order is???

The front bank is 2-4-6-8, rear is 1-3-5-7. Firing order is in the owner's manual: 1-2-7-3-4-5-6-8 (disregard the pre-2000 ignition coil arrangement in the first drawing.)
Each coil cassette has its own ICM, that small black module which clips into the L leg of the cassette. Pay particular attention to the spark plug boots - one may have a carbon track inside, which will short out a plug instantly.

i had the same misfire on cylinder 5 my 99 deville. I read somewhere in this forum that its the boots. I replaced that cable with an old one from my previous replacement. No more misfires. You can try it.
