After i tun off my car it ghost idles at higher RPM's for a very long time?
OK i have a 1960 Ford Ranchero with a 200ci i6 and after I tun the ignition off it still runs at its idle speed of about 600 rpm. So this isn't the normal definition of ghost idling that I've seen. The only way to kill the engine its to choke it or pull a plug on the ignition coil and I've let it go a good 20 min after turning it off. Any help is amazing, thanks!
