Code 48.
It always amazes me that the solution to a Check engine light is to erase it, and not address the problem.
Code 48 happens when the computer is trying to get the engine to a specific idle speed.
So, for whatever reason, your cars engine will not idle at the speed the computer wants.
Likely your base idle is off, which is a easy adjustment, but you may have a vacuum leak, or other things.
Also, on 94-95, the underhood fuse block has a fuse marked "fuel Injectors"
Unplugging that fuse will clear the codes.....And no muss withthe radio code.
