[V8] power drop outs

[Michele_Deltergo at KeyBank.com]

The first suspect appears to be the 02 sensor.  Just checked it is getting
power fine, problem is that it is passing almost all of it through!  At
start almost 3 volts going to 10 on warm up.  Seems to fit the symptoms of
OK running when cold (I think the ECU ignores 02 for a time) then crappy
when warm.   I thought most failed at no signal vs 100% signal, must be
shorted quite well.   Disappointing as 02 is only 7,000 miles old, but good
it that is the fix.  Unfortunately 02 is in like the original and getting
it out will be fun.
