Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Induction System
The air/fuel mixture needed for burning in the cylinders is provided by the multiport fuel injection (MFI) system. Refer to appropriate article in ENGINE PERFORMANCE for additional information.
Fuel is:
- supplied from the fuel tank by the fuel pump.
- regulated by the fuel pressure sensor.
- delivered to the injector supply manifold.
A dual damper has been added to reduce pressure fluctuations caused by the fuel injectors.
