Going to keep a spare on hand after this round of bullshit. What do you know about the variety of wideband sensors out there, specifically the 4.9 lsu sensors? I have the AEM 30-4110 with the Bosch sensor # 0258017025. Seems as though there are several different numbers available. I crossed this one to a Denso brand number which the local parts store has. I have read where some sensors may be different due to a different resistance? The Denso wants to bury lean almost right away without the engine running so I wonder if this is accurate.
