Anyone done this mod. My 01 w/ 34k has RPM hang between shifts (5 speed). I had a previous post, someone suggested replacing the ICA, which I did. The car no longer reves its self up at idle after long trips, up still has the RPM hang. I cant stand this. I found this thead and wondered if anyone has done it. If so what size hole did you use on your 3.8L. I'm gonna try it this week or next week if I ever get a day off work.
