What Happens When Your Car Needs a Tune-up

Many people are unaware of the signs they should look for when their car is in need of a tune-up. That's why it is important to know your car and be aware of when it isn't performing like it usually does. If your engine is misfiring or your car is showing a decrease in fuel economy, these are signs that something is going on with your car and that you should get it checked out. These are a few of the signs to look out for to determine if your car needs a tune-up.

  • An old oxygen sensor can trigger your check engine light and decrease your car's fuel economy. Engine performance might also suffer due to worn piston rings or by restrictions in the exhaust system.
  • The check engine light is on. This could signal a problem with the emissions control system and may affect fuel economy or engine performance.
  • Your engine misfires. This is when spark plugs ignite at the wrong time and is caused by worn or fouled spark plugs. You may notice your car driving more sluggishly and hard starting.
