Do you have a scanner hooked to it to read the ECT voltage?
The information from the ECT sensor ONLY goes to the computer.

Well I'm assuming, because whenever I work it hard, it get hotter, like the gauge. Also like said before it'll move up a tad bit when a/c is on/off.
I've noticed the truck runs alot cooler and it doesn't even generate alot of heat anymore. Can hear when the water pump engaged when I first replaced everything. (Radiator, thermostat, water pump, both hoses)

The ETC sensor has nothing to do with any gauge, it only sends temp information to the computer. The ETC sensor has two wires on it.
The one for the TEMP gauge is the temp sender and it only has one wire going to it.

Just a suggestion, My old Ford did the same thing and it was my EGR valve sticking. When I shut the engine off, it took awhile to fully close. I don't know why it did that. It could be jamming up, or the Vacuum regulator for it could be failing. I remember hearing a whistling noise too I just blocked mine off and never bothered checking it. That is like a big Vacuum leak and will cause sluggish low powered driving and bad/stalling idle.

But I can turn my truck off then on and it'll run perfect and idle perfect. It's got me stumped! In one of the post a guy said the TPS resets every time you start it up. So I think it might be that.
I don't know, I'm really thinking of selling it honestly. But if I can fix this problem within the month, I'll keep it. I'd hate to part with it.

You could have a funky computer...I replaced mine and had codes come up that were never there with the old one. Maybe your computer is at fault with the on/off thing you do. Swap in a reman if you try it, cost about 120. for me, Car-quest...try taking off the battery neg cable for a half hour.
