Just picked up my "new" 88' Pontiac Fiero GT, V6 5-speed. The owner before me took great care of it. The check engine light kicks on after driving it for a couple of hours ,If i restart the car it goes away. Previous owner mentioned it and said it didn't mean much . I'm thinking the computer might overheat or something along those lines and am thinking about putting in a fan . Thoughts? It does seem warm around the center console where the computer is.
