Thre report said that the OBD is not ready. The mechanic gave me a print out, asked me if I had recently disconnected the battery, and told me to drive it for 70 miles and come back for emmission . I drove it for 500+ miles and went back twice and still not ready What could be the cause of OBD not ready? print out says catalyst = not completed evaporative system = not completed Honda accord 98, 4cyl 300+k miles

 

Do both highway and city driving. Also cold start then drive the car at least 6 times.
