David, 

Thanks for the tip - checking that this afternoon!  One thing I have
discovered (or a couple of things actually) is 1) if I hold my foot on the
throttle to maintain 1000 rpm the car doesn't die - there's a revelation!
but I will get little bumps, like misses but stiffer (harder feeling).  They
seem to come about 1/3-5 sec and  2) this will sounds stupid but the oil
pressure gauge needle spikes (heads for max pressure) just before I feel the
bump!  Now I do see those oil pressure spikes occassionally and don't feel
the bump too.

I do not see any of this if 1) I'm accelerating to the point of being in
passing gear, 2) my foot in completely off the gas (coasting).

If it could just be a little wierder!

Rick
