How long does it take for plugs to show a change? Do I need to key it idle for so many minutes after reaching operating temp? If I drive it for x miles or y minutes, will that be enough?
I know that going WOT then turning off the motor immediately and coasting to a stop is the "right" way to read plugs. This really won't work for me.
