Agree the 02 sensor is probably toast, but the reason may be the water temp
sensor on the back of the passenger side head. It's a $20-30 dollar part,
and it can be tested. I don't have a V8 anymore and I gave ? sold ? can't
remember what happened to my V8 manuals so I don't know the resistance values.
Anybody got the numbers for our upside friend :)
