first the speedometer went out about 2 months ago and now the car when it warms up it will cut out when i get to a stop but when it is cold it wont. and when i get to a stop and keep my foot on the gas a little so it wont stop in traffic when i go to take off it will have a cloud of smoke when i drive off. so i have my car parked for know because i was reading the manuel. and im not sure where to start. i have had the car since it was brand new. one owner (me) and the only thing i have done is a timing belt and an alternator and battery tune up and i do my own brakes and the tune up and the alternator. but if i can get pointed in the right direction on this problem i think i can get it done. thanks
