What can result from injector fouling?

Decreased engine performance is a direct consequence of injector fouling. When injectors become fouled, it typically means that they are obstructed by deposits or contaminants, which prevents them from delivering the proper amount of fuel to the engine. This can lead to several issues, including a rich or lean fuel mixture, incomplete combustion, increased emissions, and overall poor engine responsiveness. As a result, the engine may produce less power and exhibit rough idling, stalling, or hesitation during acceleration. Addressing injector fouling is essential to maintaining optimal engine performance and efficiency.
