H3 Cylinder #2 MISFIRE

[djflacoent]

So I got this misfire code on my 07 hummer h3 now. My understanding is I would have to check the ignition coil #2 and the spark plug under that coil correct? Also that The cylinders are numbered front to back, starting with #1, land then #2, so on to #3, #4, & #5 in the rear.

There goes the 5 ignition coils. I just got cylinder misfire #2. So I'm going to check the 2nd one from the front and change the coil and spark plug if I have to.

The*firing order, or the order in which each cylinder sees spark/combustion, is 1 - 3 - 5 - 4 - 2. These aren't the numbers of each cylinder, they are the*firing order.
