[V8] Fault code 2341

[Ingo Rautenberg]

Phil,

Glad to help.  I would unplug the 02 sensor first.  The engine will run on a
default program.  If it is the 02 sensor, you'll likely get better fuel
mileage with it unplugged.  You say Australia.  Did you convert for us over
here from liters?   I hope that's not Imperial Gallons!  Has it gotten
cooler where you are?  You're looking at winter soon, correct?  How about
the thermostat?  Engine warming up nicely or slowly?

Can't help with the manual, but i'm sure someone here can :-)

Ingo
