My check engine light got on and i connected my autoscanner and i found the P0404 code.
My dodge has 49700 miles.
I checked on the internet and it is about the EGR Valve.
SHould i clean it or remplace it?
Or should i do something else?
Thanks in advance

Waiting for empty your gas tank and fill up with 93 high octane .
Run one hour then code P0404 gone .
One month two time fill with high octane .I don't see Code P0404
Try it . Good luck
