THANKS in advance to all.
Word has it that the chain store Auto-Zone will do a scan for you. For many vehicles 1995 and older there are some cheap ones you can buy for 20 bucks but have to do a lot of reading because you are really buying a book - but I've had luck with them.

Do you have a current "check Engine" or "Service Engine soon" light that either flashes or stays on?

If so - post as much as you know about it AND how the veh runs - well or not, it can help with a fix. Good luck,
