			ive been idling in closed loop (14.7 afr) for the past 6 months or so.  timing is about +3 degrees, about 900rpm.  it will hunt, but never had it stall on me 
		
		
		
		
		
		
		
		
			now the question is, what gets better fuel economy, idling at 13's AFR with smooth idle or 14.7 AFR with hunting idle? Last edited by 88turboii; 03-02-2011 at 07:53 AM.  |
