Toyota Highlander Check Engine Light
The dealer service dept. says that the diagnostic showed no clear cause(?)but I need new spark plugs ($240),ejectors cleaned, and of course the cost of the diagnostic ($130) The total was around $475. Am I being ripped?? My big question is what will they do to get the light out?? Should I disconnect the battery abnd reset the clock and radio buttons to see if it goes out? Then I can worry again if it comes back on.
