RX8 Sputter at Idle, Rough Idle No CEL
2004 RX-8 Manual, good compression on motor, only 60K on everything. The idle is VERY rough and it sputters so bad when I'm idleing. When I keep the RPMS above 1K with the gas pedal the sputtering/hiccups stops. The sputtering is hard to describe, it's kinda like the noise of it sucking in too much air or air pocket popping, or just a quick dip in RPMS, wish i could give it a better description.
Coils are relatively new and BHR so they are okay, plugs are 5,000 old, i took them out and they look okay, connections are good on the boots. I smoke tested the intake for a vaccum leak, no smoke escaped so that seems fine. IDK what it could be, any ideas? maybe the MAF sensor? When i unplug it things sound a bit better, but it still sputters.
Some of the rough idle is from motor mounts which are going bad, but not sure what the sputtering is from.

Coils should be good... they are the BHR ones so I can't see them giving out already after only a few thousand miles.
MAF sensor could be bad too, I made sure there was no gunk on it yep.

I proved it does nothing a few years back when used the normal way. Distilled water ingested with the engine running is more effective, cleaner, cheaper, and doesn't foul the plugs.
