SOURCE: Firing ORDER FOR THE 2006 chevy Uplander Van 6

There are 2 6 cylinder engines for that year. Both are the same as far as wiring/firing order but gave you both anyway(see below). There have been times that I thought I did the same thing as far as the firing order and have been doing it for 25+ years. Sometime i did and sometimes I didn't. So if you find the wiring is correct and you seem to have a miss, In about 90 percent of the time that this has happened to me I had knock a vacuum hose off so you might want to start there if they are right. It sure sounded like a miss at those times but was vacuum. There are other factors but that's where I would start if this is the case. I hope this helps and good luck.
