I recently bought a '96 sportage and can not get it to pass smog inspection in California. The meter that the smog place uses keeps showing that the sensors aren't ready. I was told to drive it (including the KIA dealer) which I have. 237 miles at highway speeds. Took it for a retest and the same thing. Ism there something I can do or that needs to be repaired. I need to get this car registered!:confused.
