I have a 1997 Pathfinder 3.3 L 2WD automatic with 156K (No trouble codes, repaired a few issues non-related to either of these items) Driven the vehicle over 750 miles and unable to get the two monitors to complete...tried to simulate the conditions at my local Smog shop, using the rollers and watching the speed.
Anyone got an idea on how to get the EGR & Catalyst monitors to switch over?
