so i've got an Innovative wide band sensor and gauge to suit ( basic option ), i've set it up, calibrated it and its been working fine for 3-4 months, although now i'm getting random readings through out the air fuel ratio.
the gauge might display correctly for a little bit then will hunt from 8 to 22.1 and get stuck on 22.1 until the car is restarted and no the car doesnt lean out and stall when this happens.
i took out the sensor from the dump pipe and re-calibrated it which only fixed it momentarily and the problem came back after a day or two.
i'd like to know people's thoughts/ ideas on this issue ?
