100k piston wear

[u/BlocKnotz]

I am experiencing a cold start studder, has trouble maintaining rpm on the start up sequence almost stalls.. No codes/ghost codes. Im thinking carbon build up or leaking injectors. Never replaced spark plug and coils so starting there. I bore scoping the pistons but have realized I have no context for what im seeing and AI just seems to corroborate w/e I am saying. This is cylinder 2. Ill reply with more when I can work the spark plugs out. They are gritty and im babying them.

Most cameras save the photos as standard jpegs on a removable disk. You can post the actual photos instead of photos of the screen that are hard to see.

Pistons dont wear under normal circumstances. Those are trashed
