I kept going here only because it was the closest. I have been to a couple of others and discovered it was also the slowest. The last time after sitting for 15 minutes and nobody moved I left and went to another one near the Chinese Cultural center and got in and out.
Also, one time the gas cap failed and everything else passed. So I went down the street and got a new gas cap and came right back to get tested again at the same station with the same technician. The gas cap passed but this time the car did not! By the way the original gas cap did make a seal. You could hear the air rushing in when it was opened. They told me a bad cap could make the car pass emissions. Bull!!! I spoke with several mechanics and found out this is impossible. I will not ever go back to this location ever again!
