I have a 2006 CE 200 with a VT-365 that the engine does not shut off immediately when the key is turned off. The engine will run for a few seconds before is slowly shuts down. All other electrically components, ie, dome lights, fans, heaters, ect. go off immediately. So that should eliminate the key switch. We have replaced both ignition relays. Any thoughts?
You are lucky and be happy it started LOL. Sorry ;) I have one doing the same thing but never have the time to look into it, mine is just a second or two. My *guess* would be injectors leaking?
