If that goes bad will that cause an engine to shred. Daughter away at college had an O2 sensor go bad and I told her to just drive it till she could make it home over summer. Now it sounds like her engine is shredded and I'm just waiting to get the call from Hyundai explaining that they are not going to warranty it because the O2 sensor was never fixed.
