Where can I find a vacuum system schematic?(the underhood is illegible)
There aren't took may sites that have schematic's available for older cars. I know Autozone has info for newer Corollas on their site, but I'm not aware of any sites that would have schematics for older cars. You may have to buy the repair manual (they are usually available at the local library too, worth a shot). Good luck.
