I know it isa elementary to most of you but I made an error while wiring my SR20DET. There are 3 wires on the o2 sensor. The middle [white] wire is shielded, for grounding static electricity. You need to make sure the inner wire is completely seperate from the outer shielding [ground]. I had 1 little stand touching and it caused a lot of headache.

My symptom:

Car was running Extremely rich.

I replaced nismo FPR, O2 sensor, and ECU all before redoing the wiring.

Hope this can help someone.

PS: There are other shielded wires like the o2 sensor one. I believe MAFS, and CAS Cam (crank) Angle Sensor are also shielded.
