2017 LTZ Z71 Saga Continues

[KungfuWerewolf]

Four month's ago I had a full engine replacement for cylinder/piston damage. Well after 4 months on the new engine cold start/rough idle p050D code and another p0300 misfire code show up after just under 4k miles on new engine. Just got a call from the dealer and its injectors again, same thing I brought it in to them before the engine replacement, they aren't sure how many and which yet but he will call back when he hears more.

 

How in the world is a "NEW" engine with 4k miles on it already having injector issues? I do like 90% driving on highway not like I am doing any crazy off-road stuff. Put 89 octane in it since I bought it in January. 

 

I really do love the truck and how it drives when I have it lol. What can I possibly do to help this dang injector issue? Total miles on this truck is just a little over 40k and supposedly now 2 injector problems already. If this is going to be a normal thing I will 100% sell this truck as a constant 1100$ injector problem is just insane for such low mileage.

Contamination in fuel tank?

When he calls back to confirm which Injectors I am going to ask about that.

The in tank fuel pump deteriorates and a bunch of crap goes through the lines and messes up the injectors and ends up messing up high pressure fuel pump. I had it all replaced under a warranty.
