Truck Problems

SO, my truck decided to start slowly killing itself about a day ago.
I got the error code P0404. I've now got excessive amounts of white smoke if I touch the gas pedal. If I try to give it a lot of gas while its sitting there, then it will cutout some and blow even more ridiculous amounts of white smoke. I also couldn't hear the turbo even begin to spool up. I just tried disconnecting the EGR valve to see if it would do anything, and I still had all of the same things happening.
Anyone have any ideas?

Try to determine if the white smoke smells like coolant or diesel.

Drive it, park on a "decline", and pull the EGR valve to see if there is moisture under it.

I believe that code is egr related.

Do you still have the stock egr system? Any coolant smell? Coolant loss? Or coming out of the exhaust?

Do you know your oil or coolant temp?

I think your egr cooler failed.

Problem solved, I took out the EGR valve, and it was basically a block of carbon, so I cleaned it out and the truck immediately ran better! Thank goodness that did it

if the concern happens again you may need to remove and clean the intake and replace the egr cooler
