2015 ram 1500 5.7L startup hesitation

[TCGM087]

I have a 2015 ram 1500 for the past year my truck has a sputter only on cold starts, wierd thing is in the winter months starts up just fine, now that summer is coming its starting to do it again! Taken it to the dealership they swap the fuel pump and same problem still. The other day i started rpms shot to 1000 then drop to 500rpms and sputters for about 5sec then shot up to 2000. But after the first start it will run fine all day long... Here is a video of what i mean....

First thing that jumps out at me is the idle air control valve maybe flaky.

Yeah, not normal. For the love of god, please show the tech/service manager the video, in case the truck decides to behave when it's in the shop.

Good luck!

Ok so had my truck at the shop since thursday i beleave they did get a sputter didnt know what too do but today i got it back so far she is running well this is what was done to it or the description on the form... C/S engine runs rough and sputters upon start up and dies at times check and advise flah updated PCM software from AC level to AD Level as per TSB 18-037-15 complete also reset 02 sencors and relearned ETC cam and crank retested good. Service manager has talked to chrysler and they are working on a fix.... So far like i said she is running well but i will update in a week on hos she is still running.

Ok so my truck is running amazing now had to switch to 88 octane from shell was running 91 and she did like it.... Havent had any issues once they did the update and started using 88 octane she fires right up. Anyone havingthis issue i wld recommend trying what they did.
