Read about the MAF connector in many previous posts and STabilitant22 also in TexasOil's posts.

Clean the MAF connector and MAF pins, crimp all 3 as shown in the pic to get a tight connection, and lube it all up with dielectric grease when you're done. Your pins should look like the one in the middle and probably look like the one on the left right now. The connector should fit tight and have little up and down wiggle when it's clipped in.

Do this first and then clean the MAF per the instructions in the Tech Help section at Q45.org.

And to add to what Brian stated, read up on MAF issues (Search word: MAF) and maybe even scan through the first page of threads in this forum. There's a lot there pertaining to the new Q owner. Good luck.
