Autotech gave me an exorbitant estimate that I could not afford. A friend recommended a mechanic at K and B Auto Repair, so I went to him and he went and bought the parts I needed, showed me the cost of each part, and then charged me $115 for labor which is reasonable, fair yet sadly very uncommon for mechanics. He saved me $400. Please don't waste even $100 for the diagnostic check at Autotech, they are trying to sell parts and they also tack on labor for each part needed, making extra money on people who can't afford it.
