So I was just cruising on the highway yesterday when I noticed that my wideband was reading completely lean. My car was running fine with no issues. What happens is I’ll be cruisin 55 on the highway barley on the gas and the wideband reads completely lean. As soon as I left all the way off the gas it’s still reads lean as it should. But when I get back on the gas for a split second the wideband will read 13-14 (normal) and then goes right back to lean and reads nothing. The only solution from what I’ve read is a bad o2 sensor. Any ideas or help is appreciated. Thanks
heres a video too:
