Where is the EGR valve on a 1998 Pontiac Sunfire 2.2L engine?

The EGR valve on a 1998 Pontiac Sunfire with the 2.2L engine is located on the intake manifold, usually near the back (firewall side) of the engine. It's often a small, rectangular or cylindrical valve with a vacuum line connected to it. However, the exact location can vary slightly depending on the specific engine configuration.

To be absolutely certain, you should:

* Consult a repair manual: A Haynes or Chilton manual specific to your 1998 Pontiac Sunfire 2.2L will have diagrams and precise locations.

* Use an online parts diagram: Many auto parts websites (like AutoZone, Advance Auto Parts, etc.) allow you to select your vehicle's year, make, and model, and then view diagrams showing the location of various parts, including the EGR valve.

Be careful when searching for the valve in person; the engine compartment can be hot, and there are many hoses and wires around the intake manifold.
