You want issues? Move to California. Smog guys love the OBD2 code-throwing machine. OBD1 is the "dumb" system-- you either CEL or you don't. You can literally take the light bulb out and pass the visual... on 96+, they plug in the computer-- you throw even one flag and you fail. That's a hassle I can do wthout, particularly on a 9+ year old car.
