Reasons Why Your Vehicle Lacks Smooth Acceleration Or Feels Like Its Bucking Have you been noticing that your vehicle does not have smooth acceleration? Don't ignore this. A jerking or bucking  vehicle is often an early warning sign of impending problems.  At One Stop Automotive we can help get to the bottom of what’s going on with your vehicle. There are some common reasons that come into play. * Dirty or Clogged Fuel Injectors Most gasoline will eventually cause dirty or clogged injectors and carbon buildup. This can reduce the injector functions, which in turn will in turn cause poor and uneven acceleration which leads to the bucking feeling.  * A Dirty Air Filter A vehicle air filter obviously becomes clogged/dirty during use. This is when the car cannot breath very well and the engine begins to struggle. The engine may start to buck while it is struggles. We recommend changing the air filter once a year ... read more

At One Stop Automotive we can help you get to the bottom of things and can get the mass airflow sensor working the way it is supposed to work. What is a Mass Airflow Sensor? The mass airflow sensor is located near the air filter and is an important part of the fuel injection system. It is designed to measure the volume of air flowing into the engine intake. This is very important because it regulates the air/fuel ratio mix for the engine. Signs of Failing Mass Airflow Sensor (MAF) 1. Check Engine Light (CEL/MIL): The check engine light is the first indicator of component failures. The warning light on the dashboard will illuminate to alert you of vehicle system issues. In this case you would usually get a code for a failing MAF.  The issue may be caused by the sensor itself failing, bad wiring due to rodent damage or a few other things.  When you have a Check Engine Light It is important to take the vehicle to One Stop Automotive for a diagnosis so this issue can be resol ... read more

Summer a can be a joyful time in Arizona, filled with the smell of mesquite trees, cactus flowers and Torrential rains. But it’s also a season of sweltering heat. The high temperatures in Arizona can push your car’s air conditioning to its absolute limits as you drive to your favorite restaurant or a friends home.

Vehicle manufacturers have maintenance schedules that should be followed at the very minimum. Having worked at a dealership in the past and still having many contacts in the automotive industry, we would recommend more maintenance. I have been told that the manufacturers established these maintenance schedules to show a lower maintenance cost over the life of the vehicle rather than for increasing the life of the vehicle. During the sales pitch, the dealership will show you that you can go 100k before certain services are due. This is not entirely accurate. Modern vehicles run much hotter than older vehicles and should actually be serviced more often. Some dealers claim you can go a full year without changing engine oil. It's your vehicle and you can do as you choose, engine oil should be changed at a minimum of twice a year or at most, 6000k. Modern vehicles have computers that monitor oil life, and many are set to alert you to change the oil at 7500 miles. We frequently see vehi ... read more

Its Arizona Car-B-Que Season As Arizona residents, we all know the horrors of jumping into a hot car during summer months, while wearing shorts and putting on those red hot sunglasses. First, after you have sought medical attention for the seven layers of skin you have lost from the back of your legs and possible permanent branding to your face from those sun glasses, we can look into summer vehicle maintenance for your sun baked car.  During the summers in Arizona when temperatures regularly reach around 100-120 degrees, the temperatures inside of your vehicle can easily reach around 150 degrees. Some people have even claimed the temperature in their vehicle MUST be around 1 million degrees, but most likely those are exaggerations. But we use these examples to make it easier to understand the affects of our severe weather on vehicles.  Summer heat and sun cause some serious damage, the worst to plastic and rubber components, ie... tires, belts, hoses ... read more
