Have a 2002 Porsche Boxster S 30,000 miles store the car for the winter took the car last week for a clean air exam and failed based on lack of information in the computer drove the car for a week just regular City Driving took it back today a week later and failed again for the same exact thing how much driving do I have to do in what type of driving

 

I didn't pass CA one before because one of the systems didn't do the readiness check yet. The smog guy told me to drive it on the freeway then come back. After I drove on the freeway for a while at speeds over 65 and brought it back, it passed. See if driving on the freeway for 15 miles or so will get it to pass.
