Jigging the throttle return spring for more tension... didn't fix the
issue. (I hope there's not too much tension on it now, the extra
tension does pull it back much more than before I shortened it
(skinny spring under the IdleSTvalve.))

However cranking down the idle adj. screw did. It's lumpy and a bit
surging but around 850 rpm. AC on bumps it up to 1000 rpm. Turning
the steering wheel drags it to 500 and lights the low oil pressure
light but it hasn't stalled yet.

Q: Can you pull off the plug wires at the dist. cap w/o bodily danger?

Q: I got 19 mpg or so on a 95 mi trip... does that rule out major top
end problems like a burnt valve or cylinder not firing?

Q: I have no idea about the history of this van... but it seems to
have a lot of grunt.

I'm kinda shocked in 2nd gear 3.5k pulled really hard considering the
weight of the van. What I do know is it has r134 fittings, new
compressor, at least 217k mi and someone replaced the valve covers
with stainless steel "scat" covers... http://www.evwparts.com/
