CHUCK'S AUTO SVC

They checked the on-board computer, which yielded a code from the vacuum sensor for a leak. They did the tune-up (including full complement of filters, spark plugs and wires) and changed out the gas cap which had a cracked seal (the usual cause of vacuum leaks on this model). The only charges were for the tune up labor and parts plus $5 for the gas cap. Two weeks later the check engine light came on again. I returned to the shop. They checked the codes again; the same code was coming up. They suggested a detailed search for this intermittent leak. I set up an appointment and brought the vehicle back. They spent 4 hours searching for and found and repaired a small crack in a tubing behind the engine in a hard to reach location. They charged me nothing for this second visit.
