Question about 2005 Hummer H2
Check engine control fuse and then switch the coil packs around again. Rescan, and see what you get. Then switch to different coils again and rescan.
Mine was a combination of a blown engine control fuse and one bad coil.
My friend had the same, but it was 2 bad plugs and one bad coil.

i don't know how match the cost, but it will he you, first change the position of the ignition coil to another coil also the spark plug, read the misfire code is it P032 or replace the code, if on cylinder 2 again appear the misfire check the compression, if ok go to electrical and check wires go and from to cylinder two coil to pcm, check the ground on #2 coil, if all this ok, see the difference reading by multi tester to coil reference if all good, reprogram your pcm, or replace if necessary

Usualy this happens when you have vacuum leak after air flow meter , bad flow meter or temperature sensor.Actually for this problem I would take car to mechanic shop.
