[V8] Hall sensor

[Lyddall's]

I was measuring with a test LED, and the two crank turns per distributor 
turn explain that question.  I was measuring at the distributor, but have 
also checked continuity of the wires to the ECM and they are fine.

The coils are both connected, and short of spending $250 on mew plug wires 
I have no way of testing if that is the problem.  I'm pretty sure they are 
all connected right - if you reverse 2 plug wires it gets really rough 
sounding.

I took it for a 20 mile drive this morning to see if the ECM had been reset 
and needed to do some relearning.  On light throttle or high RPM it tends 
to be a bit smoother, although cruising at 65 there was a hesitation every 
couple of seconds.

The distributor rotors appear to be lined up with the mark on the 
distributors when the crank is at TDC.

Any other ideas?
