I've hurd 2 issues for this on the RX4 one is the ECU they seem to have a problem and will be problematic in making spark on starting it will also miss periotically if your getting a miss every once in a while I would just buy a new ECU and swap them and see if that cures it.
fuel pumps not developing proper pressure and thuss the injectors don't work right
if you can put a pressure gauge on the injector line to see what the pressure is
not sure what is within specs but CSC would be able to tell you
