The water pump "gasket" is leaking...it looks like they just slapped on a bunch of silicone in there instead of using the proper gasket (it's a mess). I was going to make fun of your "handywork" if you were the one who changed it!
And if I adjust the idle, I could get it to idle normal at either cold or warm, but not both since one is higher than it should be and one is lower than it should be. But i'll definitely take it off and give it a clean...if I can get it off this time. I couldn't seem to get the connector off it the other night...it was stuck on there pretty good and it was too cold, too dark, and when I went to remove it I noticed the coolant leak
