Well, I went ahead and followed some odd advice:  I got the engine up
in revs by driving around the block (in EML 6-cylinder mode) in forst
gear, which got the revs over the magic 3000 rev mark, which means that
the hot wire in the MAF will do a "burn cycle" after the engine is shut
down and will clean off the crud.  I did this, and parked it for an hour
while I went to Fridays with my wife and got Cheesecake.  When we came
back, it started up and ran fine!

	So I took it out on the highway and reved it up some using 2nd and 3rd
and "cleaned it out" and now it runs fine.

	Rule with MAF equipped cars (M-50s, M-70s, and the M-Power engines,
possibly others) if you have a hot wire or hot film sensor, make sure
you hit 3000 revs when you drive, and they clean themselves!

What a cool piece of engineering!!  A bit of information that you wouldn't
get anywhere but here on the Digest.  Just when I thought the S/N ratio was
getting too high something like this comes along.
