New O2 sensors and--

this makes interesting reading,,
using narrowband sensors for lpg on disco

After install and running on PULP the LTFT came down to low single figures after being stuck on 25+ for some time,, and initially the figures were pretty stable. On a short economy run north to Cooroy I switched it over to LPG and it all went haywire, both banks went back to 25+, sensor voltage and STFT were all over the place.
then the sensor Voltage from one side went to zero. Hopefully thats just one of my crimps failed.

So, will the narrowband sensor cover a Lambda of 15.5-1?

apparently not,,
or at least something else is wrong as both new sensors are now cactus.

Plan B?

What do you think killed the sensors, LPG?

I really have no idea,,
engine temp range should be similar, both 1V 4 wire, worked exactly as they should after first start so wiring correct,,
