Got the MIL sunday, hooked up the Mx+ and forescan shows the P0401 - EGR A Flow Insufficent Detected.

Font Material property Parallel Paper Pattern


Research indicates that this is most likely the egr cooler core being plugged up? is this a DIY that can be removed and cleaned or does it need to be replaced? Not sure what the freeze frame data is telling me there?

truck is stock and has 141k

You can probably clean it with several bottles of brake clean, but that would take forever. I would either replace the EGR cooler or replace the guts. You can buy the improved guts for the 2015+ which flow better with a lesser chance of clogging immediately. Bullet Proof makes an improved core as well, but it will set you back about 1k. I haven't heard of many people going that route as there are cheaper routes one could take. Those cheaper routes may or may not offer mild weight reduction and an increase of spgs. You have plenty of options.
