Signs Your Engine Needs Attention

Your engine will often show signs before a major failure occurs. If you notice any of the following, schedule an inspection right away:

  • Check engine light is on or flashing
  • Rough idling or shaking at stoplights
  • Loss of power or slow acceleration
  • Knocking, ticking, or tapping noises
  • Dark smoke from the exhaust
  • Engine overheating
  • Poor fuel economy
  • Burning oil smell
  • Oil leaks under the vehicle
  • Stalling or hard starting

Ignoring these symptoms can turn a small repair into a costly engine failure. Our team at A & O Auto Care can diagnose the issue early and help protect your engine.
