When I bought my 4Runner last June, it had 80,100 miles on it. It now has 91,000. I checked the Carfax report and it says that it was registered as a "private lease vehicle". This leads me to believe that the previous owner probably didn't keep up with routine maintenance very well. Should I have a tune up done? If so, what should I have done besides having the spark plugs replaced?

 

Every 25 i do gear oils,timing adjustment if needed, filters, and spark plug check. If you just got it and had the money, I would replace the timing belt and waterpump, plugs,wires,rotor, and drive belts, and antifreeze coolant flush, tranny fluid. Doing all of these or most will leave you good till about 125-30k. If you dont do the timing belt now have it done before you hit 110k i would say.
