Hey guys I just changed my plugs in my 08 gmc Denali and I have a misfire on cylinder 8. If I'm standing if front of the truck which one is cylinder is no. 8. And to answer another question what is the firing order of these new ls engines and which side of the engine are the cylinders even and which ones are odds?

Driver side cylinders are odd, passenger side cylinders are even.

closest to the radiator on the drivers side is #1, closest to the firewall on the driver side is #7.

Cylinder number 8 would be passanger side closest to the firewall

Front of Car
1 2
3 4
5 6
7 8
Rear of Car

Firing order is 1-8-7-2-6-5-4-3
