Really like that shop, always helpful and knowledgeable. Needed a smog cert. Had to clear the check engine light from previous repair I made. And got it to turn off. But as I found out. It needed more and Mike told me to drive around so it would have something to check. AJ suggested a trip to Gilroy or 2. I went south turn right at Gilroy, right at Watsonville, right at Santa Cruz, right at Los Gatos back to Quality Tune Up. Passed smog! I was also concerned about my timing chain. Mike told me it has chain and not to worry. You can ask them almost anything about cars and they'll set you straight. So my 2007 Dodge Caliber will keep running ok if I take it to Quality Tune Up, I have been going there for about 20 years now. Happy motoring to you. Glenn Stidger
