Narrowband question

[2g2ner86]

I had a narrowband in my car for a while and recently it just stay on the highest light of rich and doesn't move what so ever. Does anyone have any ideas? (other then buy a wideband?)

you must have it wired into your o2 sensor.....your wires are wired in backwards, the positive and signal wire..i promise

From what I know check the o2 sensors or for a boost exhaust leak. Hopefully someone else can chime in! Good luck

It was working fine for a couple months. And then one day it just didn't move from rich. Cold or hot, it never moves.

If it was working fine that means it was wired up like it should have been, odds are your front or rear o2 sensor went bad and it needs replaced. Which wire did you use at the ECU as a signal wire, pin 75 or 76?

When the front O2 sensor goes bad, the car runs rich (since a dead sensor reads lean). My guess, from thousands of miles away, knowing nothing about the poster or his car, is that he has the gauge wired to the rear sensor and his front one is toast.
