When to Seek Fuel Injection Service

• Rough Idle: The engine shakes, surges, or idles unevenly when stopped, indicating uneven fuel delivery across cylinders.
• Poor Fuel Economy: A noticeable decrease in miles per gallon as clogged injectors disrupt the optimal fuel-to-air ratio.
• Hesitation or Misfires: The engine stumbles, hesitates during acceleration, or misfires under load.
• Hard Starting: Difficulty starting the engine, especially when cold, due to insufficient fuel delivery.
• Check Engine Light: Illuminated check engine light triggered by lean or rich fuel mixture codes or misfire codes.
• Failed Emissions Test: Elevated emissions levels caused by incomplete combustion from dirty or malfunctioning injectors.
