The owners manual on every vehicle should state how often the manufacturer recommends that you tune up cars, but as a general rule it is every two years or 30,000 miles, whichever comes first. Driving under extreme temperature and weather conditions will make parts wear out faster, however.
I show how to do a tune up on a 2000 Honda Civic. In this video, I change the spark plugs, distributor cap, rotor, spark plug wires, and air filter. Doing a tune up takes less than 30 minutes, and can make your car run better, and improve your gas mileage. And it's pretty easy to do it yourself.
