RX8 Sputter at Idle, Rough Idle No CEL

dimanche 10 mai 2015

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.
