Which is why I bought the thing in the first place! In my opinion, it
has paid for itself.

And if it turns out that the plug was fouled the analyzer didn't do
anything but make you nervous.

True. But if it was something really bad, the JPI made it apparent long
before I could have detected it "by ear".

Which, in aviation, means I had time enough to get it back on the ground.
Personally, I like the idea of trouble-shooting on terra firma.
