Okay so I got it back from the auto-electricians. They checked all the wiring and everything was good apart from the o2 sensor. The wires had corroded and broke. They wired it back up and it is now running on all 4 cylinders. How this caued it to run on two cylinders I do not know.
HOWEVER. I am back to square 1 with the EML light refusing to go away. This is the diag they gave me.
Fan unit relay control (fan 2) low speed - Permanent fault
Knock sensor signal - Intermittent Fault
Supply relay control - Permanent fault
Air conditioning pressure - Permanent fault
Knock sensor signal - Permanent fault
Ignition integrated phase detection - Permanent fault
Control Unit - Intermittent Fault
Injector supply signal 4 open circuit, Cylinder 3 injector control open circuit - Permanent fault
If I go back my my first readout it says it was over-fuelling; this has been tested and confirmed.
ECU or could it still be something else?

ignition integrated phase detection - thats either related to the injector or the coilpack and spark plugs you fitted, which in turn could be causing the injector fault
You can check the injectors yourself with a multimeter

As I said before they seem to be working fine but I will use a multimeter on the plugs. What power should they be reading?
