Folks,

I was driving home from work yesterday, delighting in the fact my fridge
was running happily on propane, when suddenly my van lost power. It was
so sudden my first thought was i accidentally flipped on the A/C.

Basically the van has reverted to the exact performance i had before my
VW Guru advanced the timing: it stumbles at low RPM and has no pickup at
all.

I checked the distributor... it is still tight. There is nothing
flopping around i can find.

The cap, rotor, coil, wires and plugs are all less than two months old.
Could this be a Hall Sender problem? The performance since setting the
timing at about 7 deg BTDC has been GREAT! The sudden change back to
what it is now is quite a bummer.

Thanks,
