Centennial drivers have probably noticed that the government mandates a lot of equipment on cars: emission devices and control computers, safety equipment like airbags and crash worthiness requirements. All of this is great for the motoring public in the Centennial area, but it does add quite a bit to the price of a new car.Because new cars are more expensive, Centennial residents are driving their old cars longer. The average car is now over nine years old. 68% of vehicles on the road have more than 75,000 miles/120,000 kilometers. As cars age, their performance drops, they have difficulty idling for long periods and are more sensitive to weather extremes. Fortunately today's cars are up to the challenge - but they need a little help to keep on going.Some owner's manuals don't outline service requirements and schedules at higher mileage. Of course, that doesn't mean it doesn't have to be done. In fact, it's more important than ever for Centennial drivers to stay on to ... read more

Hi Centennial residents. Let's talk fuel injectors. A fuel injector is a valve that delivers fuel to a vehicle's engine. It has to deliver the precise amount of fuel to precisely the right place, precisely when the engine needs it. The fuel also has to be mixed with air before it can burn in the engine.Fuel injectors are engineered to spray fuel in a specific pattern into the engine. (The pattern varies by engine type and design.) In order to achieve these spray patterns, the fuel must be pressurized.Vehicles have one fuel injector for each cylinder in the engine. Your vehicle's control computer constantly monitors the engine and various sensors in the vehicle.  It also adjusts the fuel injectors accordingly so that they can deliver the proper amount of fuel to the engine. As you can see, fuel injectors are a sophisticated and vital part of your vehicle's engine. Because fuel injectors are such precision instruments, dirt and contaminants are a serious detrim ... read more
