Fuel Injector Valve

The fuel injection valve is a significant component of a vehicle; it increases gas mileage while decreasing air pollution by fluctuating the quantities of fuel and oxygen that mix together to supply power to the engine.

Any of these symptoms could indicate a problem with the fuel injector valve:

  • Inconsistent power supply to the engine
  • Decreased gas mileage
  • Uneven idling
  • Increased fuel scent
  • Misfiring engine

Our auto repair technicians are able to diagnose and repair most fuel injector problems, including the most common ones:

  • The fuel injector is dirty or clogged: Fuel additives and microscopic foreign objects can cause an insufficient fuel supply to the engine or even an inability to supply fuel altogether.
  • The valve doesn’t open or close: Fuel additives or faulty parts can create clogs or buildup, often preventing the valve from opening or closing.
  • There is leaking: If other parts aren’t functioning correctly, it can cause the fuel injector to overheat and fail.

Distributorless Ignition

The distributorless ignition system (DIS) eliminates many vehicular maintenance issues by increasing the time intervals between required services. The design of the DIS is unique: instead of including a main coil in the engine control unit, it actually has a small coil that is directly attached to each of the spark plugs. These small coils are advantageous because they provide the exact spark timing that is needed to efficiently power the car. If you have any concerns with your automobile’s DIS, give us a call and we’ll be happy to provide you with the unique auto repair services you need.
