2.3L ('83-'97) MAF Sensor Screws

[max2244]

Went to clean the MAF sensor on a 97 2.3 and found that one screw is a T20 tamper resistant screw, No problem as I have a set at work.. What in the world is the other screw. ? It's just a plain head with nothing there. I took my pocket knife and ran the blade across the top and it seems to be made from plastic. Is it a T20 filled in with plastic or what ? I figured I would ask first as I'm pretty good at messing stuff up. Thanks.

I would just spray the MAF with MAF cleaner spray from where you can see it, I've done it to mine ('97 2.3) and it helped... I just undid the hose at the air cleaner...
