The weirdest thing happened yesterday....

[ProLean]

So on my 2014 2500, yesterday as I was driving and came to a stop...the engine started loping like it was going to stall. I held the brakes and it would surge momentarily and stumble and surge and stumble...all while at a stop. I thought it might have to do with my City Diesel turbo actuator that I had just installed so I turned that off and no change. Then I turned off my TH mode which I always use and it didn't seem to change it. The light went green and I accelerated like normal and the next stop it did it again. As it warmed up, it seemed to lessen a bit but being in AZ, it's not like the truck is cold...not in May anyway.
Got out of church and went home and the truck did the same thing MOST of the way home (5 miles or so) and then it seemed to lessen again. In my mind, it felt like my torque convertor was not releasing all the way and still "grabbing" the crank at idle.
This morning, I noticed my washer fluid flasher was on so I filled it up. Started the truck and it was as if nothing had ever happened! Ran great all day today. What the heck? Surely they wouldn't tie truck performance to your washer fluid levels would they? Probably a coincidence. I am going to service the transmission anyway as it's been about 45K since it was serviced.
Any thoughts would be greatly appreciated. The City Diesel actuator was worth ever penny though!

Check engine light???
Code(s)???

Has nothing to do with the washer fluid level, seriously doubt anything to do with the actuator either.

No codes at all. I didn't think it had anything to do with washer level but it did coincide with me doing that and nothing else had changed. Been acting fine ever since. I was just curious to see if anyone had this happen before. I don't want it to be a missed sign of trouble before a hot towing season.
