So..onto my next issue!! The car exhibits an erratic idling issue. It seems to be worse when the A/C is on. This car will be my son's car, so I'm working on as many bugs as possible before he starts driving.

Here's what I see/hear:
I have some video I need to look at and then I can try to attach it as well.

Anyone have any other suggestions on what I can check based on my description?
Thanks!

Here's what I see/hear:
- In general, regardless of hot or cold start, the car will idle anywhere between 500 and 1100RPMs. It is not a consistent occurrence, sometimes the idle might be steady at around 700RPM, sometimes it'll jump.
- The condition is more pronounced when the A/C is on. There are times when the revs will jump while in gear and if my foot is not firmly on the brake, the car can actually jump forward a bit.
- I did a "test" in a parking lot by placing the car in Neutral, then shifting to Drive. With the A/C on, the revs jumped when I shifted into Drive. With A/C off, the transition from Neutral to Drive was smooth with no dramatic rev jump.
- The revs tend to "hang" when lifting off the throttle. eg: In stop and go traffic, if I accelerate to say about 15500 ROM, then lift off , the car will actually HOLD that 1500 RPM then drop, sometimes abruptly, back to idle.
- This is NOT the same thing as when the transmission downshifts when slowing down and stopping.
- Unrelated to the idle issue, when the A/C is on, there is a whining noise that almost sounds like power steering, but as soon as the A/C is turned off, the noise goes away!
