Buyer beware
Do not buy wideband sensors through Amazon. First I purchased a knock off wideband sensor to save some money and it was a waste of time. Did not work at all, so I sent it back. I then ordered what I thought was a "real" Bosch wideband sensor and it too didn't work, AFR was all-over-the place. I replaced a lot of parts thinking the sensor could not be the problem. So, I switched to a used backup Bosch sensor I had from another project, and behold the car ran beautifully. I use Amazon for many different types of daily use items, but I won't be buying electronic critical sensor auto parts that could destroy an engine that required both financial and sweat equity to build. Buyer beware!
