2012 1500 5.7

[Tvealey]

All of the sudden has miss. Code indicated fuel injector cylinder 5. That injector was replaced,along with coil packs and plugs. Bad miss at idle. If you put your foot in it, it will perk up and run great for a minute then when you let off and RPMs come down, runs like sht again.

any help would be greatly appreciated.
