When you notice one of your headlights has gone out, it’s important for the safe operation of your vehicle to get it changed and working again.  Not only is replacing a headlight important for your ability to see in the dark, but it’s also vital that it be lighting your way and aimed correctly so oncoming drivers aren’t blinded.   Changing a headlight used to be something a driver might try to do themselves.  But that was back when headlights were standard sizes and fairly easy to access on your vehicle.  That has all changed with new technology and designs in today’s vehicles.  Most lamps are now LEDs, and there are different sizes, intensities, and shapes in different vehicles. Accessing those bulbs has also grown extremely difficult in some cases, and we recommend you have one of our professional technicians do it for you. It's just as important that your brake lights and side marker lights work, too, as they contribute to the safe op ... read more

Name someone you know who enjoys spending a lot of money on gasoline.  Yeah, me neither. That’s because it costs quite a bit to keep fueling your vehicle.   One way to save money on gas is to get good fuel economy, and most of today’s vehicles are designed to maximize your mileage.  But you might find you’re filling up more frequently than you used to and are wondering what can cause your fuel economy to tumble.  Here are a few possible reasons your mileage has been headed downhill. A logical spot to start is in your fuel system.  You may have a faulty fuel injector or an old fuel filter clogged with debris.  Another problem might be oxygen sensors, which measure the air coming into your engine and the emissions going out. An illuminated Check Engine light may be a sign of trouble there. Plus, worn-out spark plugs can reduce your fuel economy.  Under- inflated, or over-inflated, tires can also be a cause. Make sure they’re all ... read more

If your vehicle has an internal combustion engine, it depends on two things to make propulsion power for you to be able to motor on down the road: fuel and air.  The engine mixes the two in just the right proportion so that they can be ignited, creating a series of tiny explosions that are coordinated in such a way that your vehicle moves steadily ahead. One of the key parts to making sure that mixture of air and fuel is correct is a little tube that measures the amount of air that’s coming into the engine.  It’s called a Mass Air Flow sensor, or MAF sensor.  There are two wires in this tube, one of which is heated up with electricity and the other isn’t.  When the air flows over the heated wire, it cools.  When the temperature of the two sensing wires is different, the MAF sensor either increases or decreases the current to the heated wire to try to make it the same as the other wire. That’s sent to a small computer that tells the engin ... read more
