They have OBD1 books at all parts stores. Just ask them to show you that book, it includes all the codes. The first code 12 is just letting you know the computer is working correctly. The main culprit would be code 32 because it is the first code and that code will bring out the rest of the codes.

I just looked it up, code 32 is EGR valve failure and code 35 is IAC idle air control valve or idle error. I'm guessing it would be your EGR valve or a clogged vaccum line full of carbon buildup,new EGR valve about 45 bucks at the parts store
