Maybe newer fuel injected engines are different than carberated engines, but I thought it was bad to idle a gasoline engine for an extended period of time for several reasons. First, the engine burns richer at idle than at speed, which allows some of the fuel to rinse the oil off of the cylinder walls causing more rapid wear than running the engine at speed. Secondly, with water being a byproduct of all combustion, there may not be enough heat produced at idle to keep the water in a vapor state all the way through the exhaust system. Therefore, the water condenses in the exhaust system and starts to fill up the exhaust system and start corrosion. Water condenses in the engine block as well when the engine is cool, when the engine is up to operating temperature the oil is hot enough to vaporize the water and send it out the PCV valve.

As I said at the beginning these issues may not apply to newer fuel injected engines, but These are considerations. I, also, may be all wet as this applies to the FJ.
