95s are OBD-1. Try adding more coolant till your about 1" past full on the overflow bottle. This is a common fix. Try searching for "paperclip" if you want to learn a quick/cheap shortcut for finding the CEL codes on a 95. BTW: The error code #s are different than on OBD2. Post your CEL code here and someone should be able to tell you what it means in OBD-1 speak. Also BTW: Autozone and some other auto part shops will scan you computer for you for free. Just make sure they know its OBD1
