Still getting used to having a wideband O2 and gauge. I noticed that my AFRs on the gauge switch very quickly between 14.6 and 15.1 AFR during cruising at 60 mph and a mostly level surface. It measures very close to that during idle, too. I am just unsure if it's meant to do that or just stay at a constant 14.7 for example (if everything is running fine). Could a tiny air leak at the bung weld or anywhere before the O2 cause the reading to go to 15 like in my video? Or am I simply not understanding how the O2 operates? I know it's based on a 0-5 volt range but still. Please take a look just in case, sorry for the shakiness! Also just to clarify, I'm not asking if the actual AFRs are okay, but rather the constant switching on the readings.
