first need to know at what point did it start acting this way.
normally rotarys are very sensitive if not heated up engine tends
to flood. check to see if engines flooded first, then check for
spark and fuel. same thing happened to my rx-7 found that two
injectors were not firing due to bad grounding, which injectors
ground through the ecu(computer), determined i had a bad ecu
replaced it and runs great.
