5 Signs Your Engine Needs a Tune Up

Just like getting your annual checkup with the doctor, your car needs the same type of service.

There are a few ways to tell if it’s time to bring your car in for a tune up – if your engine is hard to start, stalls, misfires or is getting you low fuel economy — you should probably take your car into an auto repair shop.

Before getting started, your mechanic will ask you if there have been any issues with your car. Just like a doctor will ask questions about your general health, the same evaluation is important for your vehicle. This how the mechanic begins his assessment of the car.

It’s important to tell your auto technician about any new sounds you’ve noticed, different driving conditions and fuel issues.

If you’ve noticed any of the problems below, bring your car in for a checkup. Following a regular service scheduled is important for prolonging the lifespan of your vehicle.

  1. Your engine is misfiring: When the spark plugs get worn down it can lead to poor gas mileage, low acceleration and make it difficult to start the car. Typical spark plugs last about 100,000 miles.
  2. Your air filter is clogged or dirty: A clogged or dirty air filter can also lead to slow acceleration. It’s always good to check all air filters regularly to keep your vehicle performing at its highest level. Your filter may need to be changed more often if you live in an area that has a lot of dust in the air.
  3. Engine deposits: The modern-day car engine is pretty impressive. But, as fuel evaporates, residue can cling to the fuel ports they’re meant to pass through. Using low-grade gasoline can lead to more engine deposits than higher-grade gasoline. If engine deposits occur, your car might need a fuel system cleaning.
  4. You have a worn oxygen sensor: After about 90,000 miles or more, the oxygen sensor loses strength which can decrease your gas mileage and harm your engine’s performance.
  5. Your check engine light is illuminated: Your check engine light is a safety mechanism that notifies you when something is wrong in the engine control system. It’s important to bring your car in right away when you see this light pop on, in order to prevent irreparable engine damage.
