Stalling on cold start

I have a 2012 with 68500 miles. Over the last couple days my truck has been stalling and running rough when I first start it in the morning. Once it stalls the first time I can start it again and it'll run really rough again but after 30 seconds or so it'll start running much smoother. Sometimes when I put it in gear the rpms will shoot up for a second and be normal again after. Also it's throwing a P0174 and P0171 code which means it's running lean. Any help would be appreciated.

Likely the fuse 27 thing. There is a tsb that replaces it.

I checked that but the fuse was fine. Any other ideas?

"Common Problems That Trigger the P0171 Code

Control module software needs to be updated
Vacuum leaks (intake manifold gaskets, vacuum hoses, PCV hoses, etc.)
Mass air flow sensor
Plugged fuel filter or weak fuel pump
Plugged or dirty fuel injectors"

id start with listening for a vacuum leak and/or a new fuel filter

Clean your MAF sensor.



And clean or replace your Air Filter
