Possible gas cap leaking or your canister close valve not closing while the system does it's test.. couple different things to check..

Didnt you remove most of that? Check the vacuum lines that route to the purge box for cracks/leaks....

Ok... it keeps popping out of 5th while im on the freeway, just randomly snaps out of gear... its freaking me out... anyone have this issue? Is it common? Or just somethign my car likes to do to get back at me now?

Still having that idle problem... and it stutters.. and now it has backfired into the intake a few times leaving a stop light just after the shift into second. Its making all of the symtoms that it did when the MAF wasnt hooked up... 0 throttle response.. the backfire, the bogdown... And then it goes away and runs fine. *sigh* Its grrrring me...

My 85 Blazer would kick itself out of gear occasionally. It was because I was low on fluid. May not be your problem, but at least that's easy to check.

UPDATE:

Car is running ok, but i was wondering if the fact that my PCV pipe is NOT connected to anything, would that cause the first check engine light? The vacum leak one? All i have is a vent stuck on the nipple comming out of the engine. Neways, thanks for the help everyone. I kinda want this light to go off. But when it is my car runs like shyt. eh...
