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

Some Helpful Information Regarding Oil Changes.  Over the last 3 years auto shops have seen their petroleum prices quadruple. Currently an oil and filter change using conventional oil will cost between $35 and $85, depending on your area. If your car requires synthetic oil, you should expect to pay more (anywhere from $75 to $125) but you make up some of the cost since synthetic oil lasts longer and has to be changed less frequently. Why the difference in pricing?  There are valid reasons for this big span, mainly relating to your vehicle manufacturer choice of oil requirements. Conventional oil (made from fossil fuel) is the least expensive option. A blend of conventional and synthetic bases ( Synthetic Blend) is the next step up. The most expensive oil is fully synthetic. In addition: The price of your oil change will depend on a few factors, not only the type of oil used but the amount of oil required,  ... read more

Your vehicle's cooling system serves a few very important functions. It maintains the engines optimal operating temperature which is where it works most efficiently, and removes any excess heat from the engine when its under a load or outside temperatures are high.  While your vehicle is in use, the coolant exits from the bottom of the radiator after it's cooled, where its then drawn into the water pump, to cycle it back through the engine where it absorbs the heat and travels back to the top of the radiator where the cycle continues.  A vehicles cooling system is basically made up of the engine, radiator, the water pump, cooling fan(s), circulatory hoses, and a thermostat and coolant temperature sensor.  During the engine combustion process (intake,compression,power,exhaust) the fuel energy is converted into heat, which is transferred throughout the cylinder head and block to the coolant, and cycled through the cooling system via the water pump. The hose carr ... read more
