Good afternoon,
I attached the cylinder order for you.
The front bank is 2-4-6.
As far as the misfire, make sure you test the compression.

General Description
Misfires can be caused by lack of combustion in a cylinder due to absence of spark, poor fuel metering, poor compression, or many other causes. Even a small number of misfires may result in excessive exhaust emissions due to the unburned mixture. Increased misfire rates cause damage to the catalytic converter. The PCM monitors the crankshaft speed variation to determine if any misfiring generated. The PCM identifies the specific cylinder in which the misfire has occurred and counts individual misfire events by monitoring changes in the crankshaft rotation for each cylinder. A random misfire indicates two or more cylinders are misfiring.
DTC Description
The PCM measures reference event times and calculates the positive and negative acceleration of the crank wheel to determine whether a misfire has occurred.
When the rate of misfire exceeds a threshold where the catalyst reaches a temperature where permanent damage can occur. PCM sets this DTC. In case that misfire affects Catalyst damage, MIL (Malfunction Indication Lamp) will be illuminating and blinking at 1 Hz frequency. However, In case of Individual and Emission damaging misfire, MIL will be turned on when the malfunction is detected.
Especially, if injector connector is disconnected for more than 46 secs., PCM sets DTC relating to misfire and conducts the fuel-cut to protect the catalyst.
