Truck started great, idled good, than started running rough

Cleared up after a few wot runs, I couldn't tell if it was smoking or not it was dark. Only building 20psi max boost also.

Should I pull my EGR valve and give it a good cleaning?

 

yes try cleaning it
P0404 Exhaust Gas Recirculation "A" Control Circuit Range/Performance

I just dont know how you deal with it all the time Tyler

I just keep thinking you would get to a point where it would go for aways without some kinda BS


guess its a good thing you do all your wrenching yourself

Isnt this EGR Valve fairly NEW

 

I will try to clean it.

EGR valve was new about last spring.

Ill see how it looks

Thanks

 

Tyler are you still running around without a ICP plugged in , seems to me that needs to be addressed first. Then other stuff that pops up. JMHO
