Benny helped me out today--real cool dude. When you drop off your car, they offer you a ride home, and they actually have the NECESSARY tools to CORRECTLY diagnose your car. They switched out a split vacuum hose for vacuum switching valve, and they didn't charge me at all. If you want a diagnostic, don't erase the codes before you go to Super Shop like I did so they can properly diagnose the car. This business is always busy for a good reason. - 5 star review on Google
