How often should the ignition coils may be changed on a 2008 Toyota Highlanderr hybrid limited?
According to the dealer's mechanic one of the 6 of mine just died, after
92,000 miles but with no warning signs, check engine lights, or trouble
starting. Its not even clear to me this manufacturer handbook recommends
changing them at any interval, as they do for the timing chain.Yet all of a
sudden, i got many electronic warning messages, and car could only go a
few miles before it died. Apparently, all the spark plugs went bad too as a
result.
