A 1 Stop Smog, Antioch has been at this location since January of 2005. We are very proud of the business that we have established and take a lot of pride in our service. We are a Test Only Smog Station. That means we only do the California certified smog test on your vehicle, we do not do repairs. You will be able to make repairs with your certified Auto Mechanic of your choice and return for your retest. We are certified Smog Techs through the State of California.
Smog Tips: Before you go to a certified Smog Center, check to see if you have a check engine light that stays on continuously or a similar symbol. This will most likely to cause you to fail the smog test. You will need to have this cleared or repaired in order to pass a smog test. If you do have this light cleared, you will need to drive your vehicle about 60 to 80 miles to reset the car’s monitors. Let your Smog Tech know that this was done so we can make sure they are set before we do the test. This will save you time, and time is money.
