98 Cobra Coolant Crossover Sensors HELP!!!

Ok so I recently purchased a 98 cobra and the Temp gauge was saying it was overheating which it clearly wasn't because I drove it about 500 miles round trip to buy it and my tuner claims it was running a normal operating temp so it was just an annoyance at that point. Also noticed that the fan wasn't coming on when the car got up to temp. So I found out about the sensors under the coolant crossover, and decided to replace them. (Note before I get into this: I didn't undo the negative terminal of the battery due to being a simpleton, but really I was in a hurry and it didn't cross my mind) Anyway, replaced the one on the right when looking at the engine and a little coolant trickled out as replacing it, but fixed the gauge issue, car started fine, everything was perfect... Fan still didn't turn on obviously so bought a sensor and when I took out the old fan sensor A METRIC **** TON of coolant spewed out of the hole. But still replaced the sensor, top off the coolant, cool. But now, I have to pump the gas to get the car to start, sometimes it doesn't hold idle and dies, when it does run it idles high around 1300 to sometimes as high as 1900rpm. Also the fan is constantly on from when the car starts, which isn't necessarily a bad thing I guess but odd. What could it be? PATS? Wrong sensor in fan port (Left side when looking at motor)? I'm out of ideas and would like to get this figured out! Thanks!
