On average, drivers probably expect to hop in their cars, turn them on, and enjoy optimal performance with every drive. Fortunately, that’s what usually happens. But not all the time. Cars, especially older vehicles, aren’t “set it and forget it” machines. They require regular maintenance to operate and avoid causing avoidable accidents on the road.

This segment explains in detail common signs your car needs a tune-up.

Decreased Fuel Mileage

Like most automotive fluids, fuel mileage can be difficult to gauge unless the car has an MPG monitor. However, there are instances where your car’s fuel efficiency drops drastically, making it difficult to account for its fuel economy. In such situations, visiting an auto repair shop for a tune-up is best.

The auto expert will check the engine’s condition, oil filters, performance of the emissions system, and how the car drives. Poor wheel alignment can also affect the car’s gas mileage, often indicating other serious problems under the hood.

Weird or New Noises

It’s always important to listen to your car for any strange noises you’re unfamiliar with when driving. Some unusual noises may seem harmless initially but may indicate serious underlying issues requiring immediate tune-ups.

Cars have a series of moving parts that must work properly for optimal performance and safety. A screeching noise could indicate low transmission fluid, while a thumping noise may indicate some parts of the car are loose.

Warning Lights Turn On

Warning lights are one of the most obvious signs that your car needs a tune-up. It’s important to always check engine lights to learn what your car is communicating. Warning lights can mean several things, from a loose gas cap to problems with the oxygen sensors.

Drivers should always err on the side of caution, especially when warning lights turn on. Ignoring them could result in costly repairs.

Rough Idling

Cars that stall or shake when stopped with the engine running require immediate servicing. A rough-running engine could result from dirty spark plugs, loose plug wires, faulty fuel pumps, incorrect air-fuel mixtures, vacuum leaks, or clogged injectors.

It’s vital to have a professional auto expert check the spark plugs, air filters, fuel injection system and timing system for any underlying issues that may cause stalling.

Engine Misfires

A failing engine could indicate misfiring spark plugs, which prevent the engine from turning over. A professional auto expert can inspect the spark plugs and plug wires and replace faulty parts, saving you time and costly repairs.

Regular tune-ups are vital because they help you identify minor issues before they become costly repairs and avoidable accidents.
