Heater not working and running a little hotter
The stock temp gauge ushally sits right in the middle, but 2 weeks ago it started sumthing funny and would fluxuate to about 80 percent up instead of like 50 and would sum times suddenly drop back to normal. Since its florida it wasnt cold at the time, then it got cold I tried to turn on the heat and it would not get hot. So I thought it was the heater vale the hose on the way to the heater core, I replaced it and still no heat the valve is working correctly. And the heater core is not leaking or clogged. All vaccum control lines are intact and i still have no heat anybody ever experience this?

Purging all the air out of the cooling system can take a while, but following the directions that have been given you should be able to do it.
Regarding waterpumps, IMO you can't really ever completely rule them out either (although I also doubt it's the WP in this case). For example, the '96-'99 Taurus 3.0L vulcan was prone to a condition called "brown coolant" which would often just eat away at the impeller fins.

but i think its acting the way it is due to having air in the system.
i have seen a few people do work on cars and not bleed the coolant system.

I'm not trying to make you look bad but this sounds to me like the thermostadt might not be installed correctly and the sending unit is either bad or malfunctioning because of the thermostadt. I would recommend taking the thermo out again and double checking to make sure it's in there right and I only say that because I put mine in wrong even after looking at the instructions over and over. I realized I messed it up at the last second before I was about to drive it, then took it apart and put it in right. It almost sounds like the thermostadt is blocking the water flow and not allowing it to circulate to the heater core. This is just the idea I get from seeing what you posted.
