Default Injector Leaking Fuel Into Engine Bay

Okay, so, now that I have gotten a new clutch, machined flywheel, new pressure plate, pilot bearing, etc. I drove the car around a bit, and later in the day, looking under the engine bay I noticed fuel spraying from the area of one of the fuel injectors. I tried to look very quickly at where it was coming from, and it seemed it was coming from the injector for the front rotor housing. I didn't let this persist, I turned off the car so as to save to fuel, but does anyone have any suggestions for this problem? Do I need new injectors, or do I just need to tighten or fix something small?

I would pull the fuel rail and try new o-rings as a first step.

Haynes manual not showing much, how would I go about doing this, remove intake manifold for access, remove fuel rail or injector?

Yes, remove the intake manifold. If you haven't done this, have NEW gaskets ready, along with new vacuum hose and some new fuel line. The old rubber lines get brittle and break.

This is a good time for "while I'm here, I might as well..." (none of this is very costly):
  • replace injector grommets and o-rings
  • clean the contact area on the engine wiring harness ground (bad contact here can lead to the 3,800 rpm stumble)
  • clean out your EGR valve
  • clean your aux port system, if this gets stuck open or closed from carbon/gunk buildup, you'll have power issues
  • if you can afford to have your car down for a couple days, get injectors cleaned
