Repair of the month June 2022

Shawn Gilfillan • June 10, 2022

Our technicians work tirelessly behind the scenes every day and they certainly have their work cut out for them. Some days are more challenging and exciting than others, but they are always rewarding. 


June's Repair of the month:

Our super talented technician, Jay worked on this '08 Chevy Silverado 5.3 liter and the outcome was pretty spectacular. Here is a little overview. This '08 Chevy Silverado with 200k miles on it. The Client's complaint was that the check engine light was on and the vehicle was running rough at idle. 


After a full health inspection, and code scan Jay was able to read that the PCM (powertrain control module) Had a Code  p0301-Cylinder 1 misfire only at idle. After swapping cylinder one and cylinder two spark plugs and swapping cylinder 1 and cylinder 3 spark plug wires, the misfire stayed in cylinder 1. He then swapped cylinder 1 coil and cylinder 3 coil, the misfire still stayed in cyl 1.

This led Jay to hook up the advanced diagnostic scope, where he was able to conclude that cylinder 1 camshaft lobe was worn and lifter 


was sticking. Upon tear down, he confirmed what he had seen from the scope. He replaced the worn parts, with new OEM parts, and was able to bring the vehicle back to life and get it running like new again.

When it comes to car maintenance, most drivers think about oil changes, brake checks, or topping off fluids. But one of the simplest—and most overlooked—services that can make a huge difference in your vehicle’s safety and performance is tire rotation. At Automotive Magic, we like to remind our customers that your tires are the only part of your vehicle that actually touch the road. Keeping them in good condition isn’t just about saving money, it’s about protecting you and your passengers every time you drive. What Is a Tire Rotation? A tire rotation is the process of moving your vehicle’s tires from one position to another—front to back, side to side, or even diagonally—based on the manufacturer’s recommendation and the type of tires you have. The idea is to ensure that all four tires wear evenly over time. Without regular rotations, some tires will naturally wear faster than others, especially the ones on the drive wheels of your vehicle. Why Tire Rotations Matter Even Tire Wear Every vehicle puts different amounts of pressure on the front and rear tires. For example, front tires tend to wear down faster because of steering and the weight of the engine. By rotating them, you spread the workload across all four, ensuring they wear at a similar rate. Extended Tire Life Tires aren’t cheap, and uneven wear can force you to replace them long before their time. Rotating them regularly helps you get the maximum mileage and life out of your investment. Improved Safety Unevenly worn tires can create handling issues, reduced traction, and longer stopping distances. Rotating them gives you better grip on the road, especially in challenging conditions like rain, snow, or icy pavement. Better Fuel Efficiency Tires that wear unevenly create drag, forcing your vehicle to work harder and burn more fuel. Balanced, evenly worn tires roll more smoothly, helping you get the most out of every gallon. Protecting Your Warranty Many tire manufacturers require regular tire rotations to keep your warranty valid. Skipping this simple service could mean losing valuable protection if something goes wrong. How Often Should You Rotate Your Tires? Most manufacturers recommend rotating your tires every 5,000 to 7,500 miles, though this can vary depending on your vehicle, tire type, and driving habits. A good rule of thumb is to have them rotated every time you come in for an oil change. Our team at Automotive Magic always checks the condition of your tires during your visits and will let you know if it’s time for a rotation. Signs You May Be Overdue Uneven tread depth (more wear on the front or rear tires) Vibration in the steering wheel at certain speeds A noticeable pull to one side If you’re experiencing any of these symptoms, it’s a good idea to schedule a service as soon as possible. Tire Rotations and Seasonal Driving Living in New Jersey means your tires take on year-round challenges—potholes in the spring, heat in the summer, and snow and ice in the winter. Regular rotations make sure your tires are ready for whatever the road throws at you. Pairing rotations with seasonal tire checks is one of the best ways to stay ahead of costly repairs. At Automotive Magic, we don’t just rotate your tires—we make sure your entire vehicle is safe and road-ready. Every rotation comes with a comprehensive vehicle health check to catch issues early and give you peace of mind. Our technicians are trained to spot alignment problems, tire pressure imbalances, or other issues that could affect your driving experience. The Bottom Line Tire rotations may not seem glamorous, but they’re one of the smartest ways to extend the life of your tires, improve safety, and save money in the long run. By including them as part of your regular maintenance schedule, you’ll enjoy smoother rides, better performance, and the confidence that your car is in good hands. At Automotive Magic, we’re here to make sure your tires—and your whole vehicle—stay in top shape. If it’s been a while since your last rotation, schedule your appointment today and let us help keep you rolling safely down the road.
