Wouldn't suprise me actually. I got mine put back in and they joined the cable in about 4 places, because they had to extend it. Nothing but problems since. Question. Is there any correct way to lengthen an O2 sensor, using heatshrinkable inline joiners, or just don't do it? Cause where they welded it back in is like under the passenger floor/seat. So it's a fair whack longer.
