Well awhile ago i descreened my MAF and at the time it just seemed like something to do i saw a couple of guys on performancetrucks.net saying it helped. Now it seems like my truck dosen't run right well i mean it does but it dosen't feel the same and it idles funny sometimes. Ive cleaned my throttle body and the idle control valve could me taking the screen off might be causing this? I know that the screen helps straighten air flow maybe now that the screen is off its getting weird readings?

And if thats the reason why can i just got buy a screen name put it back in there or do i need to buy a new MAF i know of a salvage yard i can get one for about 75 bucks instead of a 200 dollar brand new one.
