Besides the diagnostic, my car needed the front axle replaced and a fuel pressure regulator. I took my car there for the fuel pressure regulator first, which was more involved & took 1 day to fix, but no problem, I just live a few miles away so they took me home and picked me up the next day when my car was ready. They performed the diagnostic free of charge (new customer) when they fixed the regulator & that's when they found out about the front axle. I took my car back for that & they had it ready in 2 hours. My car is running terrific now & I really appreciated the free rides that saved me the taxi fees!
