Are you sure what you are hearing is not just the fuel injectors?

STbeast.... where did you buy it?  aftermarket or Ford?   I feel the blanket would keep some engine heat off the hood, maybe preserving the paint in the long run. maybe, maybe not??  The hood does look naked without it.  

My 2021 ST did not come with an engine cover or a hood insulator blanket. Looked kind of funny with both of them missing. I did not buy the engine cover but I did buy the hood insulator blanket and installed it myself. It came with the attachment clips and looks so much better. Not sure how much it helps with noise.  Never followed up on the engine cover but it does look like a cover from an earlier year will work  

in another post about clattering noise, I did not want to hijack the thread with my own questions.  So....   1004ron... you mentioned in that post "Is this one of the models where Ford did away with the aesthetic / acoustic cover?'   I thought this might explain why I dont have an engine cover.  But then I assumed you are only joking... you are joking, right?   My 2024 does not have one.   I do see on mine what looks like cover attachment points.  Does it hurt anything to not have it on?   Was its purpose to cover up all the ugliness?  Mine also does not have any underhood sound deadening insulation.  Is it supposed to?  It's a 2024 with only 27k miles when I bought it.  It is odd both piece are not there.      

Are you still looking into this?

@Iroga did you buy an OEM harness and plug as well as the light? I have a light with backing plate on the way, but need to find a plug or wiring diagram for the 3 pins on the light itself. Thanks

Read through most of this thread. I recently acquired a 2019 Edge Titanium that exhibits the same stumble and stutter under feather light acceleration up to about 35 MPH. From what I have read in this thread it seems there are multiple possibilities. I will read through this thread again and see if I can come up with Step 1: unplug DPFE sensor and check driveability, Step 2.... and so on.   I have some other things to discuss with the place I bought it from, but that is another post...   If I drove like i did 30 years ago, I may have never noticed the problem. But under light acceleration, yup, the stumbles and stutters are there.

My advice would be to use a reliable scanner like Forscan as a first step in the diagnostics, and monitor the O2 and fuel trim data.      

I ran codes with my old Actron and my son's Blue Driver; no codes came up! I've had Forscan for a decade, but still haven't figured out how to use it beyond loading the stock info, of my 02 F150 Screw

Welcome.   The smell of rotten eggs comes from the CAT which only happens when un-burnt fuel get into the CAT which is a sign of an ignition or injector issue. If its been going on for a while you may need new CAT's by now but address the fuel issue first or the new CAT's will be toast in a short time.   The fact that its getting in to the cabin is a secondary issue.   Have you used a reliable scanner such as Forscan to check for codes?
