Hi Tom,
Thanks for the prompt re: I'd wondered what that contraption on the firewall was with the speedo cables attached to it...now I know. Is there anything I need to do to service the EGR valve itself, or should I just leave it alone? I'll reset the counter tomorrow to extinguish that damnable idiot light. Incidentally, I carpool to work with a guy that ALWAYS has the "check engine" light lit on his truck. This drives me nuts, but he just smiles and says, "It's running fine, why fix what isn't broken?" So, now you know why I must put that EGR light to rest!
