Keep Your Car Breathing Easy in Concord, NH: The Importance of a Clean Engine Air Filter Your vehicle’s engine needs a lot of air to run – in fact, it takes about twelve thousand gallons of air to burn a single gallon of gas. All that air has to be clean for efficient combustion, which is why the engine air filter is so crucial. If your air filter is clogged with dirt and dust, it can’t trap any more particles. The excess dust will bypass the filter and get sucked into your engine’s intake and combustion chamber. Burning dirt and pollen inside your engine does no good (and can even cause wear or damage), not to mention it chokes off the air your engine needs. A clogged air filter can hurt your car’s performance and fuel economy – replacing a dirty filter can improve gas mileage by as much as 10%. In short, a clean air filter helps your engine “breathe” properly, run smoo ... read more

Keeping Your Suspension in Check: Why Control Arm Replacement MattersPublished by Accomplished Auto | July 21, 2025 When you’re driving down the road, your vehicle should track straight with minimal steering correction. If you find yourself constantly adjusting the wheel just to keep your car straight, it might be more than just annoying—it could be a sign of a suspension issue, specifically a worn or damaged control arm. What Does a Control Arm Do? The control arms in your vehicle are a vital part of your suspension system. They connect the frame of your vehicle to the wheel hub and allow for smooth up-and-down movement while keeping your wheels aligned with the road. Some vehicles have both upper and lower control arms, while others may only have one type, but all play a critical role in ride stability, steering, and overall handling. Signs You May Have a Su ... read more

🚗 Diagnosing Catalytic Converter Issues the Right Way At Accomplished Auto, we believe in fixing the root of the problem – not just the symptom. One of the most misunderstood parts of your car’s emissions system is the catalytic converter (or "cat" for short). It plays a critical role in cleaning up the exhaust gases before they exit your vehicle. But when a warning light pops up for something like a “catalyst efficiency” code (P0420 or P0430), it doesn’t always mean the catalytic converter itself has failed. In fact, many times it’s doing its job just fine, and something else upstream – like how your engine is running – is causing the problem. That’s why we take the time to test properly, not just replace parts. 🔍 Why a Prop ... read more
