Is there any possibility that the vacuum lines may have gotten switched somewhere along the way?

Have you observed your flaps? I wonder if their behavior is the same.
I replaced those 2 pressure switches next to the air filter box some time ago and I hooked them up the same way the old ones were
AFAIK. The front switch's OUT line goes to the EGR, and the VAC line goes to the other pressure switch. The rear switch's OUT line goes to the EGR flap and the VAC line goes toward the vacuum pump and intake flap switch among other things.
Would anyone else care to check these lines and/or the behavior of the intake flaps?
