I have never had any problem with Autolites in a 3.1 V6 or this 3400
My problem remains, with Iridium AC's in there
continuing diagnoses..... will check fuel pressure next week.
continues to miss fire cold for 3-4 minutes and goes away after this time elapses.

measuring misfires, or throwing any codes?
Both my Aleros idle somewhat rough cold for a couple minutes at start up. Depending on the year model, the idle rpm vs run time vs timing advance differs a bit, I think the early models are smoother.
