I belive the one in the manifold is either a air intake temperature sensor, or coolant temperature sensor. The one that goes forward has something to do with emissions. can't remember what.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

The only sensor I see is the water temp. The one to the right is a fuel injecter and the one to the left goes down to  some sensor on the fram rail, I beleave it  has something to do with vapor can.

Its the water temp, the air intake temp is on the driver side under the upper intake. The connecter on to the left of the water temp is in wire loom with a vacuum hose that goes to the vapor can.

So there are two water temperature sensors on a stock 5.0 configuration? Because on the drivers side, front of the intake I have a water temp sensor/sending unit as well. It's the one that control the gauge, what does this one control?

It tells the ECM what temperature the engine is

One controls the gauge and the other is for the ECU. That sensor, the air temp and the o2s all work together to control air fuel ratio and to maximize fuel mileage.

go to page 55 of the evtm,, from there find all your sensors.

like said, the single wire "sender" sends a variable resistance  value to the temp guage.

the sensor, senses temp and its internal variable resistance is sensed acted on by the computer.
you should get a code for this if you pull codes with a cold motor even though it is not bad. 
thats why they say to pull codes with a warm motor each and every time.

two independant items isolated from eachother.
