Q: Service to a throttle body on 2010 Mazda CX-9

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
My dealer suggested a cleaning to the throttle body in my CX9. The car has only 16000 miles on it. Says its the result of ethanol causing carbon deposits. Is this to be expected every 16000 miles?

Every car should have their throttle body cleaned and their air filter replaced about once a year or every 15,000 or 16,000 miles which is the equivalent of 1 year of driving. You should figure about $1200 per year in maintenance over the first 10 years of a cars life, the first 4 years will be less, then a new set of tires, brakes front and back, shocks and struts at about 90k, it will begin to add up. It is very much worth it to properly maintain a car, so it lasts, that way you will not have to spend another $20-$30k every 5-8 years. A well kept car should last about 20 years.
