Anyone with shop stream and bit of soars time fancey taking a look through wave form?

Theirs a couple things I'm unsure if being a newbie a scoping.

One of cylinders has a few bits I'm not used to seeing during the burn time, would that maybe also point towards mechanical issue?

But also the same Channel looks as if it doesn't hold down the ground on dwell as much as others?

Can email the file.

I'm only one in our place who uses a scope so can't ask anyone in work advise

All help is appreciated
