I have a 2020 ranger and it rough idles. Doesn’t matter if it’s a cold start or if I drove it 200 miles. It always seems to have a rough idle. Does anyone have experience with this? I only have 6000 miles on it. It’s been doing it since the first day I had it.

Evan, take it back to dealer. These trucks have a very smooth idle. Bret

What gas are you using? Well known gas brand/station as well? Otherwise, take it in and have it checked.

I use Shell or Exxon only. I have an appointment set for tomorrow. Any thoughts on what it could be? I have the ford performance tune, but it was doing it even before the tune.

I had the tune on, and it was rough while it was cold.

I did a software update on the ProCal tool, flashed it back to stock, and now it idles cold fine.
I'm leaving it stock for now, although I doubt the above update fixed it, might be worth a try.

There are two TSBs for 2019s, just as an FYI:

TSB 19-2052
TSB 20-2339

It could be something as simple as a loose plug wire, bad plug, coil pack, etc. Good luck.

Well, define "rough idle". It's a 4cyl, it's never going to feel like an 8. If it's wheezing and sputtering then there's probably an issue. But "rough" is subjective and covers a lot of territory.

I definitely not knocking, sputtering, or wheezing. It just doesn’t seem smooth. That’s as well as I’m able to describe it. ?

It could be Evan. If it's not at least there's the warranty. Good luck.

Is it a random spit/stumble? Or is it rythmic consistant rough idle?
Look at the engine with hood open, is it visibly shaking?

Mine is sewing machine smooth, 4cyl do have inherent vibes though like mentioned already. I was even surprised how smooth it ran on 3 cyl when i forgot to plug in one of the coils for a sec.

Typically dealer will say "normal" if its not blatantly obvious or a check engine light is on. Result vary here though.

It’s seems to be pretty rhythmic. I was going to take it to a different dealer and see what they had to say.
