Why would a diagnostic port filled with some kind

WTF. Hope for your sake that is dielectric grease at least. I'd hate to have to plug any scanner I owned into that.

What is the History on this vehicle? How long have you owned her? Is there an issue with performance? Save a sample so it can be examined under magnification. Go to parts store and buy a can of "Electrical Contact Cleaner".. READ the Label on how to use it...and...do a goooood clean up. Let her dry before you start her up. Get back to us with results.
