Pulling valve cover today, fingers crossed that it was just only valve spring

Hopefully you tried tightening the park plugs before going through all that trouble???
If it's not compressed air getting by the spark plugs then I'd think it would be a hydraulic lifter failure over anything else.

Generally not a good sign with a noise like that.

That's not a spring noise. Even still, aren't you running stock springs? A broken single spring would mean a dropped valve.

Ive had a loose spark plug wire that made a similar sound....it wasnt completely off, just loose.

springs,spark and plug looked fine, its something else internally. I can here a tick/knock now the sputtering noise is gone and I have service stabilatrac and MIL p0305 code on.

This is not good...

I wonder if it's a vacuum leak. I believe some of the components in the traction control use vacuum, and of course a vac leak will cause all sorts of trouble for the engine as well.
If it's not that then I'm thinking lifter.
