Have 1997 grand marquis. Had problems with codes coming up for p0171 and p0174. Found problem causing them and repaired as required. Erased codes with scanner. Drove car close to 75 miles and I am getting now a p1000 code saying obd not ready yet due to cat and evap sensors not being ready for check. Is this common for this yr. Car and would it prevent me from getting it inspected in new jersey. If so, how do I repair it or how much longer do I have to drive the car for them to be ready?

What I need you to do is continue driving the vehicle for a little longer to see if that goes away. The computer may not have completed all its tests.

Let me know if it goes away in the next 50 miles.
