Today, after our monthly club lunch a few of us went for a spirited drive over calaveras rd, during the "cool down" my check engine light came on, no problem as all the gauges looked normal. When I got home I jumpered the service check connector to read the diagnostic codes off the check engine light, I read six long blinks followed by eight short blinks,however there isn't a code 68 listed in the manual? there's a code 6 for the TW sensor but there's no code 8 listed, now the manual is for '91 models, my X is a 95 so I'm wondering if there are other codes for later model years? if not, does anyone know what a code 68 is???
 
Yes later cars have more codes (OBD II).

MIL 68 = "Rear catalyst system efficiency below threshold"
 
Thanks Lud, you da man

If it's the rear cat going bad it should be covered under the warranty, I think the emmissions equip is warrantied for 10 years or longer.
