Don't hang your mechanic. My experience shows that a car can make a guy look incompentent. At 170,000 miles the potential for weirdness of problem and existence for multiple problems increases. My guess is the valve hoses were for the evaporative system? Give the guy a call and just explain it and ask him to look it over for something that may have been not connected. By accident. Sometimes talking to a mechanic in a civil but firm tone can do wonders.
If a tune up was long overdue, it can create other problems that could have been avoidable. But go one step at a time.
