2003 Toyota Highlander 6 cyl Four Wheel Drive Automatic 85000 miles
Recently I have noticed that fuel economy on my highlander has suddenly dropped. I used to get around 18 to 20 mpg and now it is more like 16mpg, with mixed driving. I have replaced the new air filter but have not seen any improvement. Any clues or suggestions.
have the same problem?
