Did you ever get this resolved. I have the same issue except I noticed that my O2 wires were just loose and hanging down instead of being in cable holder against the chassis. I assumed something must have hit it. However previous to this is had I believe P0138 code which was slow to respond code which would occasionally come on and when I reset the CEL it would sometimes be weeks when no error came back and sometimes it would be days or even same day.
Lately my RPM drops when I press the clutch and car sometimes stalls. Someone on forum had the same symptoms but, they never posted back the resolution.
Any help?

Hello, it's 2005 RSX Type S. I ended up replacing the O2 sensor (which was a nightmare btw) and the error is gone and hasn't returned. My clutch however failed and I am currently replacing both master and slave cylinders although the problem could very well be the throughout bearing or clutch itself as the car has 200,000Km and it's on original parts.
