EGR valve on 2008 ram 1500 hemi 5.7 4x4
I have been getting the P0406 code on my Dodge ram, looked it up and found out it was the EGR valve. Got it to my mechanic he ran all the tests said the EGR valve was running perfectly and doing what it was supposed to do. I also I’m getting misfires on just one side of the engine, the odd numbered cylinders. Not sure if the two are related. He’s not sure why and doesn’t want to just start replacing things in hopes one thing will suddenly be it.
anyone else have this happen?
