Message	I am having major issues locking in a tune with Nistune. My idle tends to be rather erratic and my idle AFR's like to fluctuate a decent amount. The idle is lean and this is with no vacuum leaks and the proper fuel pressure. I noticed my aac value stays very high (50-70) and I am wondering if this could be my issue. Does this never go down to zero? I feel like I remember reading that if the aac valve stays open it is like an internal vacuum leak which could very well explain my problem. '91 TT
