Loss of Power, Pulled a Couple Codes. Need Help!

[BoostedinSoFla]

So I've been driving my car to work for 3 days now and today this problem started on my way home. The car bogs and basically loses power at about 3000 rpms and up while boosting but this only happens in higher gears though (2nd gear and up). My ISC has been acting up because I'm getting major idle surge between 1200 and 2000 rpms.

I stopped at Advance Auto on my way from work and pulled a couple codes today also. I'm getting P0443 and P0505.

Just google the codes.

p0505 seems to be idle control system malfunction
P0443 is Evaporative Emission control system purge valve circuit malfunction

saved you the effort....

have you eliminated any emissions or messed with any vacuum lines. If not I would make sure you have all the hoses hooked up and check for leaks.
