You can usually borrow, rent or buy a GM OBD code scanner at most auto parts retailers. Since OBD2 has come out, the old version has been called "OBD1", but that's not what it was called when it was being used. The 1995 Eighty-Eight is a crossbreed. It uses the OBD-II connector but it is an OBD-I system. It appears that OBD-II code readers can handle this but I'm not positive.
