Ahhh, gotcha. I hadn't considered temperature differentials with only half the cylinders firing. I should have thought about that, since I'm an IT professional. Modern day multi-core processors use a balancing act to keep all the cores working to prevent such temperature differentials, and that makes perfect sense. So I agree with you 100%. They should alternate the firing of the cylinders to keep temps more even.
Who says you can't teach an old dog new tricks.
