I’ve had similar with my 2020 2.0l. All started after a real heavy rainy day, I didn’t drive it in any rain that day but prior was completely fine for the 50 miles I drove. I started it up & took off & was very erratic, rpm’s all over the place, falling on its face, starving for fuel it seemed. Turned around back home, after a bit CEL came on..next day code read for cylinder misfire & cyl 1 coil….ordered coil & plugs, it helped but still had a slight shudder in rpm’s. Was able to drive to my local dealer & they have been guessing since with ford..no codes to show, thought it was egr, replaced that-no difference. Tech is thinking maybe oxygen sensor…waiting to hear back from ford & their next plan of attack. It’s smooth until you apply brakes & it gets kinda jerky underneath ya & just at idle probably jumps a few hundred rpm up & down. Only 42k & I bought it with 22k. No issues until this & it’s quite frustrating. I left the diesel world to have more piece of mind…
