When your vehicle starts acting up a bit, it is best to rule out the simple causes first, such as a dirty or clogged GMC air filter. At first glance, it can be surprising how much a GMC air filter that is not allowing air to pass through it as it should can affect your overall performance. However, if you stop a moment to think about it, it does make sense, as the proper working of the combustion system relies on a carefully balanced air-to-fuel ratio, and if the GMC air filter is clogged, the right amount of air is not getting to the combustion system. When the exhaust leaves that unbalanced burn, the sensors are going to signal the computer to adjust the fuel level to match the reduced level of air available, which could then leave your engine hungry for fuel. That can cause symptoms such as hesitation, rough idling and running, feeling a loss of power, decreased fuel mileage and increased fuel consumption, meaning more money spent at the pump. If you are experiencing such symptoms, it may be a good idea to check your GMC air filter, as it may need changing.
