OBD II is kind of funny - it is always trying to compensate or wait before it throws a fault code. In that sense it is good - if you get a fault code with OBD II then you very likely have a problem.
Thanks for the response.... What I meant to ask was not necessarily the code, but the way the idle is fluctuating all of a sudden. After the hard acceleration, the idle problem started - when you are in park, the engine revs as if you were doing it with the gas pedal?

P0506 Idle Air Control - Idle Speed Too Low
Possible fault cause:
- IAC valve is sticking.
- Air cleaner clogged.
Perhaps the oil was not cleaned out of the throttle body after the AOS replacement?
Thanks Loren. Can you comment on why this happened a week later and all of a sudden?
Thanks again.

1999 Boxster Tiptronic
Had AOS replaced a week ago, yesterday, after accelerating hard to 80 mph, the car, when idleing, fluctuates between 750 and 1,400 continuosly until the transmission shifts to 2nd and rpm exceeds 1,400. I also have a pending code P0506.
Any suggestions? Thanks in advance.

Thanks for all the info thus far.
This past weekend, I cleaned both the throttle body and the idle control valve - the problem continues....
Question: Are there any moving parts apparent inside the ICV cavity? While cleaning the assembly, I noticed that nothing moved inside although there appeared to be a "flap" inside one of the orifices. I recently saw a picture on one the forums showing a "valve" that opened / closed.
Any advice?
