1999 Regal 3.8 Supercharged. Getting a P1404 code. I think it's EGR related. Can someone confirm... Is it easy to change EGR valve on this car?

The DTC is an EGR pintle circuit position error. Valve stuck open when commanded closed.
You can try cleaning the EGR valve and make sure the pintle moves freely. To remove just two 13mm type nuts holding it to the manifold section and pull up. Remove electrical connector first. Always use a new EGR to manifold gasket.
