Fuel Injection Cleaning Service Manassas VA

Fuel Injector Cleaning

Some would argue that regularly inspecting and maintaining the air filter in your car is the next most important maintenance item you can do after changing the oil and checking the air pressure in your tires. The importance of air filter maintenance cannot be stressed enough; it is, after all, how the engine “breathes.” In layman’s terms, the air outside goes into the intake system after dirt, dust, and foreign particulates are filtered. This blocks them from coming in and doing damage to the engine. Therefore, a clean air filter is critical to your car’s performance and fuel economy.

Signs and Symptoms of Fuel Injector Issues


A lot of things can contaminate the fuel injectors, throttle housing, air intake, valves and combustion chamber of your car. Dirt and carbon deposits can build up there over time and cause your vehicle to perform poorly. There are some common symptoms that dirt and carbon buildup are starting to affect the performance of your vehicle. They include:


  • Poor acceleration
  • Engine pinging
  • Lack of power
  • Hesitating
  • Hard starting
  • Bad fuel economy


Fuel Injection Cleaning


Coho Auto’s fuel injection service is a three-step process. The first step is a throttle body cleaning. We use an extremely potent cleaner that dissolves carbon deposits from the throttle plate and idle air control valve. This is also the most labor-intensive step because we have to take off the intake air system off to get to the throttle body.


Step two is the induction or rail service, which injects a chemical into the fuel line and intake to clean the intake manifold, the injector tips, valves, and combustion chamber. In brief, this effectively cleans the injectors, as well as the valves and combustion chamber.


The third step is putting an additive in the gas tank. An 11-ounce can of additive treats up to 20 gallons and is much stronger than what you can buy from your local parts store. It is essentially a fuel system detergent that cleans the tank and fuel lines not treated in the first two steps.
