Idle speed questions
 

That is to say, questions about idle speed, not idle questions about
speed ;-)

Ok then:

When shifting from Park to Reverse, the idle speed jumps up for a
moment then returns to normal. I've never noticed this in my Toyota
pickup (the car I've been driving for the last 16 years...)

When idling in park, if I tap the accelerator very lightly, the engine
speed rises and falls, THEN rises a small amount again on its own
before returning to normal.

Are these normal for the 4.0 liter I6 or do they indicate a problem ??
