Nissan gurus this is for you! 99' P11 (G20) Problem
 

OK,

My dads 99 Infiniti G20 started going ape shit, it was miss firing at the beginning so we replaced plugs/cap/rotor/wires with OEM units.
It smoothed out tremendously but...

Problem:
There is fuel coming out from the EGR tube that is attached to the exh. manifold.

So to me it seems that the injector is bad, right?!
Do injectors go bad and just dump fuel and flood the engine?

Yes they can. The pintle gets stuck open and sprays until fuel pressure is fully gone, you will need a new injector seal too. Those are prone to cracking alot too.
