Ok after a ton of diagnosing I've finally found something that fixes the motor. It's a sr20det with mainly bolt ons. Running a rs enthalpy j4 ecu.
While the car is idling it has a slight miss, idles right at 800-900 rpm fluctuating with the misfire. If i hold it at 3k rpm you can definitely hear the miss. However, if I unplug the o2 sensor it stops misfiring. If I hold it at 3k it runs steady as a rock. Idle sits at roughly 1300 or so. WOT is fine either way with no misfires.
Going to check the wiring tomorrow. Its a new sensor (under 200 miles). Anything else I should check? Also does anyone know the normal resistance in the o2 wiring? I checked the fsm and couldn't find anything.
