What does it do? - The fuel system transfers fuel from the fuel tank and passes it through a fuel filter for straining before it arrives at the injectors. A pressure regulator controls fuel pressure to ensure good engine performance under a variety of speed and load conditions. Fuel injectors, when activated, spray a metered amount of fuel into the engine. Some vehicles use a return line system to return unused fuel back to the tank.

Sluggish. Squealing. Unreliable. Vibrating. If any of these descriptors fit your vehicle’s recent behavior, it just might be trying to tell you something – like it’s time for a tune-up.

Today’s vehicles differ significantly from their decades-old brethren that required a tune-up every 10,000 or 20,000 miles. With newer vehicles, it’s increasingly common for manufacturer-recommended service intervals to stretch to 100,000 miles before certain maintenance items, such as replacing the spark plugs, should be completed.
