This is a strange code that doesn't appear to have one definitive reason, it's a bit of "you have a bit of a problem, but we aren't sure". Just Answer dot com mechanic says it is the MAF Sensor.
the fuel filter is it a inline type filter if so check the arrow on the filter make sure the fuel is flowing in the right direction because some of these filters have a non return valve in them.a garage made this mistake with my brothers car, hope this helps its worth checking. it sounds like a restriction of fuel
hi black smoke is not good, and you say the water level is going down. im sorry to inform you may have a blown head gasket. rough running engine lite, if you have just bought the vehicle i would recommend taking it back to were you bought the vehicle.
Sounds like computer to me , black smoke might just be due to fuel /air mixture.
Avoid dealerships , find a reputable mechanic.
Almost any shop can plug your car into a diagnostic computer .
If you live close to me , I would be happy to take an s-70 off your hands :)
it sounds like this problems is related to the ETM, or electronic throttle module. if software download was already performed, next step is to clean the throttle body bore. ultimately, the module may need to be replaced.
