Re: Drive Cycles to Clear ECM Monitors? Am I the Only One?

by E Meyer <epmeyer50@[EMAIL PROTECTED] > Dec 16, 2007 at 12:15 AM

It seems like the simplest solution would be to get them to stick the
sniffer in the tail pipe and do the inspection the way they do it for
pre-96
cars.  I wonder if they'll do it?
