Your car may not be able to tell you exactly what’s wrong, but it’s pretty good at dropping hints.
Maybe the engine feels shaky at stoplights. Or your gas tank seems to empty faster than usual. While these issues might not seem like a big deal initially, they’re worth noticing. A vehicle that isn’t running like it used to could be telling you it’s time for maintenance.
Tune-up services can help identify worn components, address performance problems, and keep your engine running at its best. Here are five common signs that your car is due for service.
5 Signs It’s Time for Tune-Up Services
Rough Idling
When your vehicle is sitting at a stoplight, the engine should feel smooth and steady. If you notice shaking, sputtering, or unusual vibrations, something may be off.
A rough idle has several causes, including broken spark plugs, ignition problems, restricted airflow, and fuel-system issues. You may also notice the engine speed rising and falling unexpectedly.
One rough idle doesn’t necessarily mean your engine is in serious trouble. But if it keeps happening, you should have your car inspected. Finding the cause early helps prevent a small issue from becoming a bigger repair.
Gas Mileage Has Dropped
You probably have a good idea of how often you normally stop for gas. So when you suddenly find yourself at the pump more often, you’ll definitely notice.
Changes in driving habits, traffic, tire pressure, and weather all affect fuel economy. But an unexplained drop in gas mileage may also indicate that your engine isn’t operating as efficiently as it should.
Tune-ups save you more money at the pump. Proper vehicle maintenance can improve fuel economy by about 4%, saving you $.019 per gallon, which really adds up.
Sluggish Acceleration
Your car doesn’t have to be a sports car, but you should know how it normally responds when you press the gas. If your vehicle feels slow to accelerate, hesitates when you step on the pedal, or struggles going uphill, something may be affecting engine performance.
The culprit could be the ignition system, airflow, or fuel delivery. Engine performance diagnostics get to the root cause of the issue. Instead of replacing parts based on guesswork, diagnostic testing can pinpoint the exact problem.
Your Car Is Harder to Start
Turn the key. Nothing. Try again. Finally, the engine starts. If that sounds familiar, don’t ignore it.
Several issues, including a weak battery, worn spark plugs, ignition problems, or fuel-system concerns, can cause hard starting. Spark plugs are particularly important because they provide the spark needed to ignite the air-fuel mixture inside the engine.
Over time, spark plugs wear out and won’t work as effectively as they once did. Depending on your vehicle and its maintenance services schedule, spark plug replacement could be part of the solution.
Engine Misfires
An engine that sputters, jerks, or suddenly loses power can indicate an engine misfire, which occurs when one or more cylinders fail to ignite the air-fuel mixture properly. Worn spark plugs are one possible cause. Ignition coils, fuel-delivery problems, and other engine issues can also contribute.
A misfire shouldn’t be ignored. In addition to making your vehicle difficult to drive, an ongoing misfire can potentially lead to additional problems.
If your check engine light is flashing, particularly when your engine is running rough, or your vehicle is losing power, have it inspected promptly.
What Does a Tune-Up Include?
Car tune-ups focus on inspecting and maintaining components that affect engine performance, efficiency, and drivability. Depending on your vehicle’s age, mileage, and condition, service may include:
- Spark Plug Replacement: Worn spark plugs can cause hard starts, rough running, poor performance, and misfires.
- Ignition System Inspection: Checking ignition components can identify wear or problems that may affect engine operation.
- Air Filter Replacement: A clean air filter provides the airflow your engine needs to operate properly.
- Engine Performance Diagnostics: Diagnostic testing can help identify the cause of symptoms such as hesitation, misfires, rough idling, or a check engine light.
Not every vehicle needs every service at every visit. Your owner’s manual and your vehicle’s condition should determine what maintenance is appropriate.
Why Tune-Up Services Are Important
If your car is still running, it’s easy to put off service. But there’s a difference between a vehicle that runs and one that runs well.
Regular tune-ups give you a chance to catch wear and address problems before they become more expensive or disruptive. And with the average vehicle on the roads now 12.6 years old, maintenance is more important than ever for drivers who want to keep their cars longer.
Think of a professional tune-up as a check-in for your engine. You’re not waiting for something to go wrong. You’re making sure the parts that keep your car running optimally are getting the attention they need and deserve.
How Often Does Your Car Need a Tune-Up?
There isn’t one mileage interval that applies to every vehicle. Modern cars have different maintenance requirements, so your owner’s manual is the best place to start.
Your vehicle’s age, mileage, and driving conditions can also affect when certain services are needed. Frequent short trips, stop-and-go traffic, and extreme temperatures can put additional demands on your vehicle.
If your car is already showing warning signs, you don’t need to wait until your next scheduled maintenance appointment. Schedule a thorough inspection as soon as possible.
