I have checked fuel pressure and it is good, but the trick is checking it
when the van is acting up.  This is particularly difficult since I need to
be in the engine compartment to check the fuel pressure, but I need to be in
the drivers seat to start the van and push the accelerator to keep it
running!  I am going to enlist the help of my wonderful wife for this one!


CHT (temp II) sensor is good.  I have measured at different temps and
compared to a spare and it is happy.

Thanks for your suggestions,
Jake

Have you checked fuel pressure AND flow?
Is your CHT sensor good? You can check that with a meter at different
temps (ambient air vs. after a hot water bath).
