2012 G37X cylinder 5 misfire

[molonlabe]

Put in brand new spark plugs, still shows misfire. Swapped the coil from #5 to another cylinder, and it STILL shows cylinder 5 misfire. So now I'm thinking it's the fuel injector on #5. Any ideas/suggestions?

I will take out the fuel rail, check all the injectors, especially #5, and put the #5 injector in another slot, see if the misfire travels to the new slot.

But please offer any insights that might help.

Nope, you are doing the right thing in troubleshooting. The head scratcher is why would an injector go out at the same time you replaced the spark plugs and only touched the coil packs and plugs? Car is being stubborn.

***UPDATE*** In looking more closely, I noticed the wire harness to the injectors was chewed... Sure enough, taking apart the fuel rail, the wire leading to #5 coil was chewed through - a chipmunk or something... Replaced the harness, car runs like a champ.. Starting my Q70L yesterday, the SAME exact thing happened, and it makes sense - both cars have identical engines, so whatever critter did this, went to the same spot and chewed the same wires... Anyone know a good chipmunk trap??
