[s-cars] Speaking of plugs? (not A/S)

[Mark Strangways]

The problem with reading spark plugs is that in order to get accurate
mixture readings you need to pull a high speed WOT run and then shut it down
before you come off the throttle. You cannot start it till you have read all
the plugs.
If you don't follow this procedure then any readings will not show accurate
results.
Unless you are looking for gross problems, not tuning.

Where I live many bad things would happen if I tried to pull a 4th gear WOT
run and shut down right after :-)
