Stein: I'm more worried about the cold shock from super rich AFR so if Paul is running his idle at 10.5 I beleive it will shorten his sensor lifetime.

It is NOT a good idea to do a sensor warm-up prior to starting the vehicle.
Depending on the climate and the sensor position in the exhaust, condensation can
form in the exhaust pipes. This condensation could then be blown by the exhaust
stream against the hot sensor when the car is started. The resulting heat shock can
permanently damage the sensor.
