Fuel Injectors - GM Genuine Parts

PRODUCT FACTS

Find out more about ACDelco GM OE Fuel Injectors and how they fit into the Fuel and Engine Management System with the product facts below.

Function:

Sprays fuel into the engine’s intake manifold or cylinders.

Signs Of Wear:

Sluggish engine performance, poor acceleration or emission noncompliance.

What It Does:

The Fuel and Engine Management System supplies the proper mixture of air and gasoline to the engine while reducing harmful fuel vapors and exhaust pollutants.

Service & Maintenance:

Make a service appointment if your vehicle shows any of the following symptoms:

  • Illumination of the “Service Engine Soon” light.
  • Improper engine idling, hesitation or stalling.
  • Excessive exhaust smoke.
  • Abnormal engine noises.
  • Noticeable fuel odors.

The fuel filter should be replaced according to the maintenance schedule shown in your Owner’s Manual. Also, have your engine tuned up regularly. A plugged/restricted fuel injector (if equipped) can reduce fuel efficiency.
