    Could me many issues. Personally I have found that the first thing I check is the O2 sensor then the catalytic.

    Its not to old to get scanned, you just need to find a shop/someome with a scanner capabile of scanning older trucks.

    You need a scanner that can scan OBD-I trucks.

    Isn't there a trick with a paper clip that will get the truck to give you the code in the form of a flashing light? I know there is a post on here about how to do it.

    Some older models allowed you to turn the key on then off then on again and the flashes of the light would send you in a specific direction to troubleshoot
