And 124 transitions in sixty seconds elapsed, 2.1l @3000
rpm.  140,000 miles, old sensor -- unknown whether original.

Now I'm bummed.  I really want that sensor to be sloppy and bad and
all manner of evil.  Replacing the traitorous revolting thing should
cause my motor to run perfectly and give me 20 mpg at sea level.

Am I doomed to disappointment?  Or can I figure out a way to decide
that the test is inadequate, so I can replace the sensor without feeling silly?

Or am I doomed to spend $70 and some swears purely as a sacrifice to
the gods of magic?  The magic doesn't work if the price isn't enough
to hurt -- but $70 is still worth twenty bucks, even today.

Well, gentle readers?  What would *you* do?
