One of the most common symptoms that indicate the need for a fuel injection system flush is poor engine performance. If your vehicle is experiencing rough idling, hesitation, or a decrease in fuel efficiency, it may be time to consider a flush. During a fuel injection system flush, a specialized cleaning solution is introduced into the fuel system. This solution helps break down and remove any carbon deposits, varnish, or other contaminants that may be clogging the fuel injectors. The cleaning solution is circulated through the fuel system, allowing it to reach all the critical components and dissolve any buildup. Once the cleaning process is complete, the old solution is drained, and fresh fuel is added to the system. Regular fuel injection system flushes can help maintain optimal engine performance and prevent potential issues down the line. By removing deposits and contaminants, the flush ensures that the fuel injectors deliver fuel efficiently and accurately, resulting in smoother running and improved fuel economy.
