2017 5.3L with 50K miles started to run rough and get P303 then P050D and P2101. Ran much better after warm up. All indications were for replacing all injectors. $600 for  labor at dealership and $600 to $1000 for parts was my guess.  

 

Drained gas tank to start. Gas looked normal. Ran better but not right.

Decided to try a few tanks of expensive Shell V-Power® NiTRO+ Premium Gasoline. 

Ran better and better. 4 to 5 tanks later and no check engine light. Now at 70K the truck is running almost perfectly. Just a slight hesitation sometimes at low rpm. 

I am not affiliated with Shell but the magic stuff worked for me.  Hopefully I can put off new injectors for now.

 

Just thought I would share my experience.
