Where is the EGR valve on a 1999 Pontiac Sunfire 2.2?

The EGR valve on a 1999 Pontiac Sunfire 2.2L engine is located on the intake manifold, typically near the back, towards the firewall. It's usually a small, rectangular or cylindrical component with a vacuum line connected to it. However, precise location can vary slightly depending on specific engine variations and modifications.

To be absolutely certain, I highly recommend:

* Consulting a repair manual specific to your 1999 Pontiac Sunfire 2.2L. These manuals have diagrams and detailed descriptions that will show you exactly where it is.

* Using an online parts diagram resource. Many websites (some require a VIN) offer detailed diagrams of engine components for specific vehicles. Searching for "1999 Pontiac Sunfire 2.2L engine diagram" can help.

Simply searching visually isn't always reliable, as access to the EGR valve can be hindered by other engine components. Using a manual or diagram will greatly improve the accuracy and safety of locating it.
