Can't hold idle
 

Around May my 04 mt rx-8 was having problems holding idle. starting the car cold, it would be fine, but once the car warmed up and i engage the clutch, the rpm's drop straight to zero. I reset the ecu and replaced the maf and that fixed it for a while. Around end of june it was having more problems and now will not hold idle at all again. i have been out of town since then and just got back and am working on it again. there isnt any loss of power that i can notice except it is running very rich. i am waiting on the mazsport ignition solutions and new spark plugs. could this fix the problem? anybody have any other suggestions on how to fix this?
