'99 Suburban 5.3L - Code P0404
'99 Suburban 1500 4WD 5.3L
The "service engine soon" light popped on this morning, and I pulled code P0404 via my handy Actron OBD II scanner.
The scanner indicates code "P0404 EGR Flow CRKT".
What's my next step in tracking the problem down? Is there a EGR valve that I can replace?
Thanks
Bill
