ok. so my balt has been acting weird lately. so when i have the ac on blowing on high the car seems to jerks every 8 - 10 sec for about 20 min and i can feel the power being lost and gained when it stops jerking. and when the car idles the fans kick on and off and my rpms fluctuate irregularly. i will get a video up when it starts doing it again. anyone think they know what it is? its not the TB cuz i cleaned it a few days ago.

It's your ac clutch. Mine used to do this and it was only a noticable problem while at idle or going slow. I just didn't use the AC unless I was moving.

Unfortunately I dont know if there is a solution.

hahaha good one. well my dad looked at it and he thinks its the ac compressor. so instead of me paying 350 for a new one I'm gonna let chevy do it for me.

had chevy look at it and it turns out there was too much freon in the system, so they did a complete ac system clean for me. cobalts hold .9 and mine had 1.4 in it lol.

A/C is one thing I leave to the professional guys with the proper tools. If you don't know what you're doing, have someone that does do it for you.

^^This. As you can see you CAN over fill it and it will cause a LOT of issues, especially if the issue isn't spotted fast enough. If your AC isn't blowing cold, check your Cabin Air Filter (it's behind the glovebox for those that don't know) and it could be clogged, not allowing enough air to flow through the AC Core for your blower, and that could actually cause it to freeze. IF that filter is fine, then take your car to a shop to get AC service.
