2017 Big Horn 5.7L runs roughs when slowing to a stop

[Quiganomics]

My 2017 Ram 1500 Big Horn has recently started running rough when slowing to a stop, fells like its chugging/misfiring. Once I'm completely stopped it smooths out and is fine, same when under acceleration...Only happens in the process of stopping. No CEL, no codes have set. Any ideas?

How many miles on it?

Not a mechanic but my first thought is a dirty throttle body. If that checks out check your throttle position sensor.

Like Huntergreen mentioned, if you haven't cleaned the throttle body it would be a good place to start. Don't clean it on the truck. Remove it first. There is a good step by step posted on this forum if you search for it.

Have you ever used a fuel system cleaner? Could be dirty injectors.

The plastic intake is pretty famous for the gasket leaking. Check around yours for leaks. Mine had oil seepage around the back passenger side so I retorqued mine a few times when it was newer as the gasket seems to shrink/crush with heat cycles.

Dealer did a fuel injection cleaning service back at 45k. I looked and see no signs of oil leaking along the intake. Sprayed brake clean along gasket and around vacuum hoses with truck idling, no change in idle to indicate a leak. This just has me confused....possible that the torque converter could be causing this or am I maybe being paranoid over nothing?
