Got a tune up for $200 and they only changed my plugs and threw in some engine cleaner in my gas tank, car ran fine before this so called tune up but I thought I should get one since I was close to 100,000 miles. Within a month it was bogging and missing. Took the car back and they told me the computer said the car was fine and that the wires were bad and they recomend to have them changed at 100,000. They did not do this during the tune up why? Wires dont go bad within a month and I was almost at 100,000 miles when it was done. They then told me it would cost $400.00 for them to change the wires and put in a new fuel filter which should have been done during the tune up itself!! Then they had the nerve to charge me $44.00 for the diagnosis after screwing me for the tune up in the first place. I wouldn't trust them for my car needs if my life depended on it. $400.00 to change wires.....give me a break!
