Your Check Engine Light is On — Don’t Panic!

It can be alarming when your check engine light pops on. But, there is no need to panic. There are numerous things that could be going on that require minor maintenance. If your light is steadily blinking it could be a major cause for concern with your engine, but a steady on light could mean less invasive repairs are needed.

  1. Check your gas cap. The gas cap helps maintain consistent pressure for your fueling system. It also helps keep gasoline from evaporating into the air when you aren’t driving your vehicle, which will not only help the environment but save you money at the pump. So, if your gas cap is broken or lost, replace it as soon as possible.
  2. Your Oxygen sensor may need to be replaced. A faulty oxygen sensor can cause damage to your spark plugs and catalytic converter, making your car burn more fuel than necessary which will cost more money at the pump eat into your gas mileage.
  3. Your catalytic converter may have gone bad. A bad catalytic converter will reduce your fuel economy and cause your vehicle to run hot.
  4. It could be time to replace your mass airflow sensor. A bad sensor can cause damage to your catalytic converter, oxygen sensor or spark plugs and not allow your vehicle to measure the right amount of fuel needed to run your engine efficiently.
  5. Spark plugs or wires may need replacing. Spark plugs ignite the air/fuel mixture in the combustion chamber while the wires deliver spark from the ignition coil to the plugs. Damaged plugs can cause your catalytic converter to clog or cause damage to the oxygen sensors, all of which can cause your engine to have a loss of power or run poorly.

Several culprits can cause your vehicle to display a check engine light. Starting with these five will help you weed out any other possible malfunctions and get you on your way. If your check engine light is on, drop by our service department - we're happy to take a look for you!

Safe Driving Series: Railroad Safety

A quick Google search of Memphis railroad fatalities yields tragic and startling results - far too many are killed or seriously injured in train-car collisions each year. These tragedies are easily avoided, however, by following some very basic train safety rules. According to the National Safety Council, you are 40 times more likely to be killed in an accident with a train than with another automobile. Remember that trains do not always follow set schedules, so when approaching a track, always expect a train to be nearby. It isn’t safe to stop closer than 15 feet, so be mindful of the lined barriers in front of the tracks! Here are a few other tips to help you and your loved ones stay safe on roads near tracks:

Safe Driving Series: One of the most important tools to use while driving – Your Eyes

It is no secret that one of the most important things when it comes to automobile safety is clear vision. But, you may be surprised to learn that every state has different standards when it comes to licensure. In Tennessee, for example, original applicants (not renewal) must pass a vision test and have a visual acuity of 20/40 or better. If you do not have good vision you are required to see your optometrist and get corrective lenses and return with a note. You will then be issued a restricted license that requires you to wear your lenses while driving or receive a ticket.
