[V8] Timing belt change - follow up

Well I got the timing belt completed, thanks for the recommendation to use
BlauParts, their kit and tool rental made it nearly a breeze.  The kit was
amazingly complete with seals, pulleys, fluids etc.  I also replaced the
fan and oil pump bearings, because like everyone else said, I was in there,
might as well.

I used this for reference while I was doing the work, proved very helpful:

It was nearly the same, just different Dizzy setup on the back of the heads.

I also got my leaky power steering fixed while in there, thanks again
spokanehose, that was the third hose I've had them done, worked great.

But there's always something....

I ended up having to trim about 1.5" off the end of the drivers side of the
top radiator hose, hose clamp pinched through it causing a leak.  Glad it
was there and not elsewhere in the hose so I didn't have to replace it.
 But the one remaining issue I'm having is keeping me from getting it back
on the road. It's only throwing one code: 2111.  Which based on a search of
the list archives is likely the crank position sensor.  Strange.  I just
replaced it and it's partner about 3 months before the water pump gave out,
so I'm pretty sure the sensor is still fine.  Behavior is it starts and
idles just fine, slowly increase the RPMs and around 3k it starts to act
like it's skipping or stumbling.  When trying to drive, similar behavior,
idles along just fine, try to give it some throttle and it'll stumble and
sometimes stall.

I tried peaking under the dizzy to see if maybe the plugs had come loose
while I was putting the cam lock plates on/off but they look plugged in ok.
 I haven't tried re-seating them just yet since there's quite a bit of
engine bits in the way there and I was losing sunlight.  Thought I would
see if anyone had any suggestions for something to check besides those two
sensors hidden behind the drivers side header.

Only other noteworthy item is on the passenger dizzy there's a sensor that
the plug socket had crumbled a bit, I cleaned it up and made a clamp of
sorts to hold it in place, could that be my issue?
