M42 Won't Idle, Some Backfiring [EDIT: Photo Dump Of Broken Stuff]

Seems like it would be better to look into aftermarket or custom made dampers for that price.

Possibly. This is such a critical component, both for engine reliability/longevity and fundamental ECU operation that it is definitely not worth using anything that is not of the same quality as OEM though. A custom one that was properly engineered would probably cost $500-1000.

I had a nightmare of a time diagnosing my no start issue, to the tune of 2+ months (it's not my daily so it wasn't extremely critical), but it ended up being the damper. There's a thread floating around here from 2017 describing my process, it sucked.
