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

We have many very long term customers as well as new ones. Over the course of our years in this business we have noticed that people understandably do not like to spend money on automotive repairs. Who would? The problem with this can be multifaceted. A small repair, if not addressed in a timely manner, can blossom into a very expensive repair. We had a customer in the shop yesterday for an inspection. We found that all of his engine and transmission mounts are broken, needing replacement. Originally, when we had informed him of this last year it was a single mount and a minor repair that the customer chose not to have us take care of. Now because the single mount was not replaced, it over stressed the other mounts and they failed one after the other in a domino effect. In addition, the broken mounts are causing major stress on the axles due to the engine and transmission sagging.  Its crazy the way little things can snowball into such major things. This why we always try to kee ... read more
