Just started throwing a code. Can anyone explain to me what this is...? i assume its some type of emmissions valve. How to i fix it? or do i just get it reset, and see what happens?

P1404 EGR Valve Closed Pintle Pos

on an 07 - 5.7 hemi. Any help would be much appreciated!

 

You're egr valve is either dirty or just bad. Probably more trouble than it's worth cleaning it and hoping it works. I'd just look at replacing it, then reset your pcm.
