Title: One or more bad o2 sensor(s) out of 4...
Product review: I ordered 4 - 2001corvette o2 sensor's and one or more has failed. The plug in read out I used does not show which one is bad, just that I have a bad o2 sensor. Less then 25 miles. Cleared the DIC and eng lite come back on. Will now have to spend $$$$ to find out which ones...There goes any savings.....
Would you say this review depicts the product in a flattering or unflattering light?
