Does Your Vehicle Need a Tune-Up?

Posted November 3, 2023

Over time, as your vehicle accumulates miles, its performance and fuel efficiency can start to decline without proper maintenance. If you notice certain signs and symptoms, it may indicate it’s time to get a comprehensive tune-up service at your local certified auto shop. Let’s take a look at some of the most common issues to keep an eye out for.

Decreased Gas Mileage

One strong indicator that your vehicle is due for a tune-up is steadily decreasing gas mileage. As spark plugs slowly become fouled from combustion buildup and air filters get increasingly clogged with debris, the engine has to work significantly harder to deliver power, using more and more fuel in the process. Closely monitoring any drops in your gas mileage over consistent routes provides insight into engine efficiency. A noticeable decrease in your usual MPG may warrant a complete tune-up service.

Lack of Acceleration

When you notice it takes longer and strains the engine more to accelerate from a full stop or pass other vehicles, it can signify issues like severely clogged air and fuel filters, old worn spark plugs that won’t fire properly, or failing fuel injectors. These prevent the engine from getting the ideal air-fuel mix and spark for rapidly generating power. A certified mechanic at a reputable auto shop can diagnose these issues and replace worn components to restore strong acceleration.

Rough Idling

If you notice your engine begins frequently sputtering, hesitating, or vibrating while idling at stop lights or stop signs, it likely means the engine is idling roughly and unevenly. Misfiring cylinders or lagging ignition combined with intake components being clogged can disrupt smooth idle. A full tune-up helps re-balance the ideal fuel mixture and ignition timing so your idling smooths out.

Strange Exhaust Smells

Unusual burning odors, excessive exhaust fumes, or high hydrocarbon smell when idling or accelerating can also indicate issues needing attention. This may stem from oil leaks, damaged oxygen sensors or catalytic converters, or problems in the combustion chambers. Don’t ignore strange smells coming from the exhaust — have your trusted auto shop thoroughly inspect the engine and components to identify any needed repairs.

Periodic tune-ups per manufacturer recommendations are crucial to keeping your vehicle running at peak efficiency and can prevent much larger mechanical breakdowns or failures. According to Zippia, there are over 920 thousand Americans who work in the motor vehicles and parts manufacturing industry. This means there are many auto shops you can visit when you need maintenance or repairs. Of course, not all auto shops are equal in quality, so it’s important to make the right choice.
