Started car a couple of days ago, ran until warm and turned key off. Engine continued running with key in any position - on, off, accessory. Not simple dieseling or run-on. Only way to stop is by turning key to off, holding brake and putting in drive or getting out and pulling coil wire off. Replaced ignition switch to no avail. Any group thoughts as to problem and cure ?? Any help will be greatly appreciated. I'm no expert with auto electrical.
Side note: NAPA was closed so I bought the ignition switch @ Advantage Auto for $4 less and swapped out the tumbler.
