What is this? "Tune Up" is a term that may mean different things to different people. Customers will often call asking for a tune up and this can mean anything from an inspection, checking fluids, or a general look over. What a mechanic hears when they hear the term "tune up" is a very specific maintenance service. A tune up will typically include: - changing spark plugs - changing fuel filter (if serviceable) -changing air filter (as needed) -changing spark plug boots or wires (depends on vehicle) -throttle body service -Mass air flow sensor service - Optional: fuel injection service
When: We recommend this service be done according to the maintenance schedule in your owner's manual or advised by licensed technician. Typically anywhere from 60,000 kms to 100, 000 kms. This is a larger maintenance item but if budgeted for over the 3-5 years between services will not be as overwhelming. For example: If vehicle tune up costs $600.00 every three years that is $120.00 - $200.00/year. Cost:Every vehicle will be different. Contact your mechanic shop for an accurate quote.
Why do I have to do this? A vehicle's engine needs a combination of fuel, air and spark to operate well. Too much fuel, too much air or inadequate spark can all create engine malfunction. A regular tune up will ensure your vehicle is able to combine air, fuel and spark in balance. Spark plugs are little devices inside the cylinder that take in high voltage electricity at one end and create a spark at the other end. There, the spark ignites the gas and air mixture, and the resulting combustion is what ultimately powers the car. One of the main parts of this service involves removing the old spark plugs and replacing them with new ones. What happens if I don't do this? Your engine will start to misfire and run poorly, performance will suffer, efficiency will decrease and emissions will dramatically increase. Your car may also be difficult to start.
Car Care Tip: On some vehicles it is possible to pull a spark plug to check the condition of the spark plug. This is something you want checked if you are buying a vehicle because tune ups are expensive and important. The spark plug will show if you can expect a large maintenance expense sooner than later.
