My o2 on display at program showing 32:1-23:1 usually on idle is 23-27 when wot, it show 32 back up to 27-23, then let gas off showing 17 for few second then back to 23-27, check voltage in program showing 0.03v idle, on it around 0.32v roughly. 2nd o2 disable, and set on factory o2. No cel, heater and response is on.


Installed o2 sensor 234-9005 denso, wideband, using hybrid racing harness, plug it in, and check the wiring it's right.
