Subject: Now what? Engine idles then revs up

Learned Brethren,

When we first started the "new" engine upon installation, there was no cat
or muffler installed so it sounded a little loud, like a stock car, but ran
at a steady pace.  Now we have the exhaust in place it sounds like a Vanagon
;o))

But what is unusual is as the thermostat opens the engine revs slightly
increase - then drop to idle - then rev a little higher than the last time -
then drop down to idle - then rev higher than last time - and so it goes on
and on getting more revs per cycle.

Any suggestions where to look for a reason for this?
