Problems With Idling and Cooling, Many Pics of Stuff Not Plugged In

[alex99gst]

Alright, so I did some research with the Virtual Tour of the DSM website before this, but I need as much help as I can get. The car runs like crap now, the water temp. gauge inside the car doesn't even move after 3 hours of interstate driving , the radiator light thing whatever comes on now. Before it would go off after filling it with a little coolant, but not anymore. On top of that, the car idles bad and it fluctuates all the time and drops below 500 on occasion. I will try adjusting the BISS soon and see if that helps. Today in traffic, the car stalled for the first time ever, so I start it and rev to 3 and let out and it still stalls . After a while it drives OK with the coolant light on still. Finally get to work and everything under the hood is extremely hot, including the UICP I guess you get what you pay for. Now to what i took pictures of:

So this is the Idle Switch and someone cut it right off WTF

Where does the plug with the red and orange wires connect to?

Where do these two plugs go to up by the firewall?

Any help is greatly appreciated as I am very concerned about the flaming hot engine with the radiator light coming on and no water temperature gauge.

Just click on the different quadrants of the car and then you can click on the individual red dots to get a better picture of the location.

That is what I used to figure out what some of the things were, but I have no idea where any of them should be plugged in at or what i need to hurry up and figure out to fix the coolant problem. I also just noticed today that all 4 vaccum hoses off of the throttle body are unplugged and were just pushed under other wires. Should I cap the 2 middle ones off atleast since that would cause a vaccum/boost leak?

The first one is the the Closed Throttle switch, the third one is for the fan, teh 5th one is your wiper motor. On the Thermosat housing there is 3 sensors the top one is for the AC, then there is a sensor with 1 terminal it is the sending unit for your coolant temperature gauge, and the last sensor is the CTS for your ECU.

Looks like a fun, good luck

On the thermostat picture, I can see the part that goes to the ECU and it is plugged in and fine, but right below it there is something that is rusted and I saw a plastic piece that connects to the throttle body through a hose. Is that what is wrong and something is supposed to be plugged in there?

Im going to go try to run the vaccum lines like the taboo diagram and see if that helps out with anything.

So just now i plugged up the throttle body and the lines coming to and from it and i found a little piece that looks like it attatched to a part of the thermostat that had broken off.

Did I do this right? Also fixed the Idle Switch thing

If so, I think it was this. Part # MD103807
