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...
Loss of power and white smoke in higher RPM's???

Any high pitch noises? Maybe a turbo going south.
sounds like you have a bad injector or two, white smoke is excessive fuel, past black smoke, so much fuel it cant burn it all. Keep driving it this way and you will lose the engine this much fuel washes past the cylinders scores the cylinder wall and get into the oil. Have it checked out right away.

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.
