Also what is the failure rates of coils and the module on the underside of the plenum.
If the tank was that low it may have picked up some not so good gas. Try some injector cleaner and a run through a tankfull of gas. To check a plug miss I pull the plugs and put the boot on, lay them on the plenum and crank the car, all plugs should show the same spark color/intensity.

To check for fuel flow look at the plugs when you have them out to make sure they are all the same color. Check by switching the plug to a good cyl and see if the plug 'cleans up' and the other has change color. If its black leaking inj if its too brown lean condition/bad plug.
