[V8] V8 cutting out at about 1800 rpm

Before going too far with this, the no-code status should be confirmed.  Can't see a dealer getting none, but I'd want to see it with my own eyes.  A bad hall sensor and/or distributor and/or distributor cap all throw hall sensor codes.  So do the flywheel sensors.

If confirmed 4444, then (and only then) would I move on... right down to my other first thought -- the temp sensor on the back of the head.  I don't recall if the wire for it passes near those of the flywheel sensors where they could have been buggered.

And speaking of which, has there been any report back on the flywheel teeth (or hopefully not lack thereof)?
