A Bluetooth OBD-II code reader is cheap enough, assuming yours is OBD-II (it... should be, 1995 or 1996?).
Those are worth their weight in gold when troubleshooting cars. Nothing nicer than the computer telling you what's wrong.
More fun than, say, troubleshooting a 75 year old tractor that won't start in the dead of winter and you want to use it to plow your driveway so you can get your truck out... ended up bashing my way through snow drifts to go get new plugs.
