With today’s modern cars, the term “Tune up” is a bit outdated. Back in the day, cars had ignition points that would wear out, and need replacement annually. Spark Plugs would wear out too, as well as the distributor cap and rotor. Replacing all these parts would constitute a Tune Up.
The only ignition parts that today’s cars have in common are the spark plugs. With the increased technology , spark plugs now last upwards of 90,000 miles.
Other tune up parts would be the Air Filters and Fuel Filters. Your air filter still needs to be replaced every 15,000 miles or more often depending on where you drive. Fuel Filters are usually part of the Fuel Pump nowadays, which is inside the gas tank.
Higher mileage cars would benefit from doing an a Decarbon Service to remove built up carbon deposits from behind the throttle body, in the intake manifold and the tops of the valves. This will restore smooth idling and restore your gas mileage.
Also doing a Fuel Injection Flush will help too. We will push cleaner through the Fuel Injectors to help restore lost power, smooth idling and gas mileage too.
Although todays car are much more reliable, needing less repair than yesterdays cars, they still require maintenance to run well and deliver the gas mileage and power the manufacturers designed them to have.
