1988 Volvo 240 DL.Please Help.
 

Okay so long story short I went driving in snow and the second day of the snowstorm my car starts idling rough and losing power. Eventually it starting having really bad problems it wouldn’t even go over 10 mph and would just fall on its face giving gas. With a lot of smoke and smell of gas. So I replaced mass air flow sensor as a start because the idle wouldn’t change after unplugging it. But now it will start, no more gas fumes. But once in drive or given any throttle. It dies. What I was thinking was fuel issue?( Filter, Pump, Relay) or Clogged Throttle Body? But to be honest I really don’t have a clue.
