2007 Toyota Camry throwing oxygen sensor lean condition after filling up with Costco 87
I recently switched to filling up my 2007 Toyota Camry with 87 Costco gas after filling up with 89/91 for the the past 14 years at Shell/Esso. I know it's highly unlikely, but the first time the code turned on, I filled up the tank with 91 and the light didn't come back on after I reset. I tried my luck with 87 a second time and the code came back on immediately I made a stopped and turned the engine on.
Is this just a coincidence? Or am I actually onto something?
I should also add that I recently replaced the oxygen sensor that is throwing the code.
Thank you in advance.
