Yes, I actually rode around with him while he was tuning. He would get it straightened out, and it's almost like it relearns the problem. Like I said, I did check for leaks around the intake manifold and CAI with starting fluid and got no fluctuation in idle. I would think if it had a vacuum leak it would be constant.
