Though some of the components of a Tune Up have changed over the years. The goal is still the same, to have a reliable and smooth-running vehicle. 15-20 years ago, a tune up consisted of replacing the distributor cap and rotor, spark plugs and wires, replace the air filter and in some cases the PCV valve (Positive Crankcase Ventilation). Automobile technology has advanced to the point where individual ignition coils have replaced distributors. So, what does a tune up consist of? Today it is just replacing spark plugs and your air filter. Performing regular maintenance, from fluid flushes to cabin air filters is even better! This is all to give your vehicle the best chance to provide you many miles and years of great running and reliable service.
