When the engine light illuminates, it can be alarming, signaling that something is amiss under the hood. Understanding the common reasons for this warning can help you take timely action and avoid costly repairs. At Roswell Transmission and Car Care, we provide expert check engine light diagnostics and repair in the greater Roswell, GA area. Here are five common causes for the check engine light to turn on. Faulty Oxygen Sensor Oxygen sensors play a crucial role in monitoring the level of oxygen in your vehicle’s exhaust system. If the sensor malfunctions, it can lead to poor fuel-economy and increased emissions, prompting the check engine light to turn on. Replacing a faulty oxygen sensor is typically straightforward and can improve your vehicle’s performance. Bad Catalytic Converter The catalytic converter is a vital component in your vehicle’s exhaust system, converting harmful gasses into less harmful emissions. If it becomes clogged or damaged, it can cause a significant decrease in engine performance and fuel-efficiency, leading to the illumination of the check engine light. Worn Spark Plugs or Wires Spark plugs and their associated wires are essential for igniting the air-fuel mixture in your engine’s cylinders. If they become worn or damaged, it can lead to misfires and decreased engine performance. A check engine light may illuminate to alert you of this issue. Replacing spark plugs and wires at manufacturer-recommended intervals can help prevent this problem. Loose or Damaged Gas Cap One of the simplest reasons for a check engine light to turn on is a loose or damaged gas cap. The gas cap is designed to create a sealed environment for your fuel system. If it’s not properly tightened, fuel may evaporate before your engine gets the chance to use it. Mass Airflow Sensor Issues The mass airflow sensor (MAF) measures the amount of air entering the engine, allowing the computer to determine the correct amount of fuel to inject for optimal performance. If the MAF sensor is dirty or malfunctioning, it can lead to poor fuel-economy and performance issues, triggering the check engine light.

The suspension system in your vehicle plays a key role in maintaining stability, handling, and comfort on the road. When your suspension is compromised, it can lead to a variety of issues that affect both the performance and safety of your car. To avoid bigger problems, it’s crucial to recognize the early signs of suspension trouble. At Roswell Transmission and Car Care, we provide expert suspension repair in the greater Roswell, GA area. Here are six signs of suspension trouble. Excessive Bouncing One of the most obvious signs of suspension trouble is if your car bounces excessively after hitting a bump or pothole. This typically happens when the shocks or struts are worn out and can no longer absorb road impacts effectively. If your car continues to bounce for a while after hitting a bump, it’s time to get your suspension checked. Rough/Uncomfortable Ride If you’re feeling every bump and dip on the road, your suspension system might not be doing its job. A rough or uncomfortable ride can indicate that your shocks, struts, or other suspension components are worn down or damaged, leading to less cushioning. Uneven Tire Wear A healthy suspension system helps keep your tires balanced and aligned. If you notice uneven or accelerated wear on your tires, it could be due to issues with your suspension. Worn-out components can cause misalignment, leading to uneven pressure on your tires and reduced tread life. Drifting or Pulling to One Side If your car pulls to one side while driving, especially when you’re on a straight road, this could signal a suspension problem. While pulling can also indicate alignment or tire issues, it’s often a sign of uneven wear in the suspension system, which throws the vehicle’s balance off. Nose Dives During Braking When your car lurches forward and "nose dives" when you apply the brakes, it could be a red flag for suspension issues. This occurs when the shocks or struts are worn out and no longer keep the vehicle stable during braking. A car that dips too much when braking could have difficulty stopping effectively, making this a safety concern. Visible Sagging A vehicle that visibly sags or sits lower on one side could be dealing with a broken spring or damaged suspension. This is especially noticeable when your car is parked on a flat surface.
