[Shotimes] HEGO sensor trouble codes

[Kevin & Cheryl Airth]

Hunter:
 Have you checked the plug wells for oil? I had the same O2 errors and off
and on stumbling at highway speeds. Resealed the plug wells and fixed it
all. This was within 10K miles of my 60K work. I reused the valve cover
seals and put RTV on them but apparently not enough! I used new seals and
RTV when I redid it!
