Double check, and then tripple check, the MAP sensor hose at the very rear of the plenum. Another vac leak source (that you swear is under the plenum and actually isn't) to check is the PCV valve hose on the driver's side towards the rear of the plenum. You might actually have to pull that hose to investigate for a crack/split in the rubber... very, very common.

Let us know.
