Response to what spark plugs?? Want to stop run-on at shut down

Ford solved this problem on their engines in the past with a electric throttle stop. It set the idle speed when the key was on , key off, throttle plates would close completely, therefore stopping “run on” These came on the engines that first received “smog tuning”. Can’t remember exact years. There are also air conditioner electric throttle stops. Of course this is just oneway to stop run on, hopefully you may tune it out. But some engines just seem to want to run on. GM, Pontiac division, iirc, turned on the A/c for a few seconds after the key was turned of to combat “run on” . Bones
