With the part I ordered required to put the dashboard back into the car on order and accidentally shipping to the wrong address, I decided to tackle the engine today. I installed new fuel injectors, spark plugs, cam/crank sensors, EGR valve, IAC valve, PCV valve, and gave everything a super deep clean. New spark plug wires will be arriving next week.
In the two cylinders that were exhibiting misfires (cyl 7 and 8) I found the spark plug wells were entirely filled with motor oil, as these wells are located right next to the oil fill hole in the valve cover I believe the oil is a result of sloppy pouring by the previous owner.
All plugs looked good and healthy except the two that were misfiring (left two in photo).
Next is to reorder the vacuum actuator for the AC controls under the dash, install new O2 sensors, fuel pump, fuel filter, and a fuel filler neck gasket.
