I have adjusted the TPS and looked at the MAF (its aftermarket and i couldnt figure out to pull the actual MAF out) and it didnt look too dirty. I just recently changed the pcv valves and hoses.

Did you get around to doing the boost leak test yet?

I hope i will be getting to it this weekend. Its been driving good recently, but ive havnt been going hard. This idle still has been jumping up and down every once in a while but it hasnt been bad enough to stall or anything. Its been bouncing from like 600 then to 1100 rpms then it idles fine for a while then bounces again. Hopefully all of this will be solved this weekend with the boost leak test.
