Routine engine health check<\/span><\/h3>\n

A tune-up is very much like bringing your car in to see the doctor for a complete exam. With time, components within your engine deteriorate, get clogged with dirt, or just cease doing their job altogether. With a tune-up, the mechanic checks out all the things under the hood and replaces what’s making the engine sluggish, allowing it to breathe more easily and run better.<\/span><\/p>\n

That typically involves replacing the spark plugs and their wires or coil boots and changing dirty air and fuel filters. They’ll also clean the fuel system and throttle body to remove any accumulated carbon or grime. They may also reset the ignition timing and replace smaller items such as the PCV valve, distributor cap, or rotor if they’re damaged. On newer vehicles, they will usually perform an instant computer scan to detect and repair any concealed engine fault codes as well.<\/p>\n

Why it matters<\/span><\/h3>\n

A tune-up restores lost power, reduces rough idling, and improves fuel economy. It can stop small problems from turning into expensive repairs. In simple terms, your car will start easier, run smoother, and cost less to drive when the ignition and fuel systems are in good condition.<\/span><\/p>\n

Modern cars versus older cars<\/span><\/h3>\n

Older cars with mechanical ignition need tune-ups more often, usually every 10,000 to 12,000 miles. Many modern cars with electronic ignition and fuel injection can go far longer, sometimes 25,000 to 100,000 miles, for certain components. Always check your owner\u2019s manual for the manufacturer\u2019s guidance.<\/span><\/p>\n

When you should get one<\/span><\/h3>\n

Follow your owner\u2019s manual and watch for signs between scheduled services, such as dashboard warning lights, poor fuel economy, hard starting, rough idling, sputtering, or loss of power. If you notice any of these, get the car checked sooner rather than later.<\/span><\/p>\n

DIY or professional<\/span><\/h3>\n

If you are skilled and can follow the manufacturer\u2019s instructions, some tune-up tasks can be done at home. But for a complete and safe job, especially on GDI engines or cars with complex electronics, professional service is recommended.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
