Could sombody posibly tell me the simtons to a air flow meter fault.

My car was runing ok untill it started to missfire then smoke a little then smoke more then it seemed as if it was running realy rich could smell lots ofpetrol
I will say i have disconected and reconected thebattery a number of times in the last cuple of weeks Now it wont start at all no fault lights on on the dash
Would this be the Air flow meter

It could be or many other things you need to have the fault codes pulled.
