black_gold_wrxsti Posted May 24 Report Share Posted May 24 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 Quote Link to comment Share on other sites More sharing options...
