hmm, only 5 in my case. I had the head rebuilt resurfaced valves etc done this spring by a local indy. He says that he put them back as they were routed, I believe him.

who knows... seems that the code would have come on much sooner though, I have beed driving the car for 2 months and it just appeared 4 days ago.

To be coupled with a 4 requires a cold start temp..otherwise the AIR system is not called for, so there is no system monitoring b/c of no AIR activation demand signal.

I highly doubt your criss-cross was there before the head work, but it is possible that you had a vac leak , in which case the vac. pressure sensor would not report back th the DM at EGR activation.
I have also seen the electric connectors get switched at the SOVs..that results in the same condition as crossed vac lines. The ECU EGR sig winds up opening the AIR valve and the AIR sig opens the EGR valve. Same problem and resulting condition, but electrical fault vs hose swap fault.
I always do an EGR manual test on 104 b/c of the known code 5 tube blockage problem they are infamous for, just to be sure. [ and it only take 20 secs]
Anyway, a good find and some attestment to tracking problems using common sense with a code.
So many think a code points to a part replacement, when in reality, it is a system fault notice ..it is then that the remedy is found by checking the indicated system. See guys change an EGR for a simple vac leak in the hose
b/c they interpet the code as bad EGR/face value.
Your tracking down the actual fault causing the code 5 is a perfect example of the correct way to diagnoses using the code storage system as a system fault guide. Good job.
