Car has covered 3k miles with this wideband and had no issues haven't changed anything at all
On recent trip out I noticed on idle from cold it was reading afr at 18.1 and lambda 1.6 I drove it 20 miles and it continues to stay at this level turned the car off disconnected battery and around 4 hours later started it up for drive home again 18.1 and 1.6 lambda took it easy on the way home .
Downloaded my ecu logs and you can see its spikes from 0.6.lambda to 1.6 over and over.
I have been told this sound ls like a failing lambda sensor ?
I have read a few concerns about these bosch lsu adv sensors not lasting too long.
Is there any better widebands out there?
Thanks
