Hello. I'm having problems with my fiat punto 2002 1.2 16v.
The o2 readings from the downstream sensor is only stable at 0.6 - 0.7 v during idling after closed loop has ended. I recently replaced the calayctic converter. Had worse readings before the replacement.
Could it be that the o2 sensors are bad even though they are giving readings?
Car runs great overall. No CEL after i replaced cat (p0420 before).
Added some pictures of the readings on a long drive (hot cat) and on idle.
Thanks.
