Well, after a couple of days' wait and $715 later, the new throttle body with attached MAF sensor went back in. The shop cleaned the EGR manifold ports while the throttle body was off, and now the engine runs perfect. Also, no more EGR code P0402.
This was a VERY costly repair for a 4-cyl base-model work truck with only 72,000 miles on it, in my opinion, and I hope and pray that there won't be more of these kinds of repairs needed.
The shop admitted that it was not easy to diagnose with the general test equipment they had/vs the actual Nissan machines; and from what I can tell by searching the threads, the MAF sensor has either never gone bad unexpectedly on other people's 4-banger Frontiers, or they are not reporting it.
Keeping my fingers crossed, now,

Val Barone
