I've got the same code reader. I'm still trying to figure out if it's helpful or not. It has given me some information, but less than totally clear. Plus I've had mechanics say that codes from OBD1 vehicles are not that reliable. Who knows. I'll keep using it in hopes that it will shed some light as things occur. Glad that it worked well for you.
