Idle On The Ford Power Stroke

A friend of mine has a 2002 F-250 SuperDuty, with the Power Stroke.

Here's what we can't figure out:

Even when the engine is fully warm, when idling the truck, the engine sometimes bumps the idle up to 1200rpm. Notice that the rpm drops to it's normal level when the accelerator is tapped. Funny thing is that the truck behaved this way since it was new...

All in all this isn't a problem, although this buddy and I were curious as to why this happens.

Advance thanks for any info that might be offered.

It's normal. The purpose is to reduce emissions and improve heater performance when idling. There's also an exhaust backpressure device that may kick in and change the sound of the engine. It's discussed briefly under Cold Weather Operation in my '01 Power Stroke owner's guide supplement. I'm guessing it'd be under a similar heading in his.
