    Ls1 going a bit haywire

    I went to take my blazer out for a drive, which I don't do as much as I used to, and the idol is wild as soon as I start it. Going up and down and when it slows down some it stays at 2000. After waiting ten minutes or so I notice that the radiator overflow hose is starting to poor out fluid. I have no idea wether or not these are related. Not sure why these would happen at the same time. Let me know what you guys think so far.

    So obviously after thinking about it a bit, I realize that it must be overheating. I looked again and noticed that the temperature gauge isnt even going up. I checked the fuses and their fine so there must be some kind of bad connection. Hopefully that's why it's not triggering the fan to turn on. The idol problem I still have no idea on.
