I seem to have a truck that runs real strong in the am after sitting all night..In the afternoon 8 hrs later it seems to be a dog? The morning temp here is about 55-65 degrees..In the afternoon usually 85 degrees? I also notice some white smoke in higher rpm's even in third of forth gear on acceleration??? Any thoughts would be appreciated...

I had the same thing, you are running the cyl contribution test at close to idle, you can't run it at high rpm when the problem shows up. Mine was a bad injector, I changed one, then it came back a week later. I then opted for a set of aftermarket injectors. cheaper in the long-run than remans.
