2016 with 116k on it. very well maintained. Outside temp was about 30deg. car sat for approx 9 hours. i went out to start it to warm up before i left work. as soon as i turned the key forward, the engine kicked on and started flooring it a few times all on its own?!?!?!? i was reaching through the pass door so i wasnt even sitting in it. Once it stopped wrapping out my ice cold engine... it sort of idled down to normal cold idle...it stumbled a bit but eventually it calmed down. this is the 3rd winter ive had this thing and the first time its ever done that. has this happened to anyone else?
