[V8] Dizzy Hall sensor, knock sensors

[John Bysinger]

Some of you have been following my saga related to a timing belt change,
and an odd stumbling at 2500RPMs.  After taking it for a little drive
around the neighborhood to see if perhaps it just needed time to get the
fuel maps figured out, I think i'm back to the Hall sensor.  I had rebuilt
the wiring and the connector mount on the passenger side distributor for
the Hall sensor, but I don't think the rebuild worked.

After the shakedown I'm getting codes 2111, 2113, 2142, 2144, indicating
RPM, Hall, Knock #1, Knock #2.  SJM recommends checking knock wiring/sensor
for the latter two, but 2113 points back to my hall sensor.

I recently replaced the crank sensor, using a VW version with a longer
cable, Is there a similar (less expensive) option for the Knock sensors?  I
would like to eliminate those as possible failure points on top of the
existing Hall sensor issue.

Is it possible to _just_ replace the hall sensor?  I haven't seen it as an
individual part listed on the parts seller websites, and the dizzy itself
seems to be one heck of a high price item to replace (if you can find one
in stock.)  A fellow lister has offered to loan me his bench dizzy to test,
I think I'm going to try that before I look into replacement, just to
confirm.  But in the mean time, any tips on where to find a replacement
would be helpful.

Tonight I'm going to inspect the harness side of the wiring that plugs into
the dizzy/Hall sensor to see if the issue is on that side, but not getting
my hopes up.

Thanks as always!
