Whenever I take the car out, the first time it gets to temperature and I'm at a stop, the fan kicks on and dims all the lights, drops the idle by 200-300 a few times, then everything goes back to normal. This only happens once every trip.

Now I noticed with the AC on at a stop the idle is wobbles 200-300 constantly.

When I turn the cabin fan on in the car it is super weak, about 1/2 of what it used to be. Randomly though it will kick on full power for a few seconds then drop down again. When my car does that first issue I mentioned, if the fan is on it kicks the fan into overdrive while the revs are moving.

I thought maybe the battery was going so I just installed a red top, but the issues are the same.

Vacuum leak? Alternator? ??


Another issue, which I'm not sure is related, or even an issue, is that when I barely push on the throttle (while in drive) the car will make a squeal that sounds exactly like squeaky brakes. I've heard it ever since I put on my CAI, and I just figured it was the TB being at the right spot to make a whistle like noise, but I have noticed it is getting louder. It happens in any gear, always at the same throttle %. It is only when the supercharger is engaged. Not sure this is even an issue, but the other issues made me start thinking it could be a leak.

Any ideas are great!

EDIT: forgot to mention that besides these minor things above, the car performs great!
