Wacky looking screw heads.
I have recently started getting a p0102 error code on my 2002 Buick Lasabre. So I thought I would pull the MAF and try to clean it but when I looked at it I see these funny looking screw heads that appear to be a tort screw with a raised point in the middle of it that prevents me from taking it off. I have looked around for a tool like it but haven't found one.
I'm wondering why it'* there and how to get them out.
Thanks for any suggestions.
