My car failed smog because of a stored memory fault.
No active check engine light. I had the faults reset
and still fails. Everything passes except "diagnostincs problem"

I'm told to drive the car a few days and about 200 miles and car should clear memory faults before a re-test.

Anyone has experienced this? It has something
to do w/ the new smog machines in No. California.
