Hello,

It will depend on the type of injection system....

If it is a CSI System - meaning it has a converted Carburator. It is located under the Upper Intake Manifold.

If it is a SFI System - meaning there is an Injector for each cylinder. It is located at the end of the Fuel Rail.

However, I am not sure that is you problem.

Is the engine light on? If so need to get codes pulled and post them here.

It could be any number of things causing you problem...

Leaking injector/s

Bad O2 Sensor

Bad Coolant Sensor

Vacuum Leak

Leaky EGR Valve

Plus others.
