Just now my SES light went on. Idle is better in drive, but really noticeable in park.
taking it in tomorrow.

Evidently rough idle can lead to a lot of things.
Since the SES came on, the car shifts from P to R rather roughly, and a loooow speeds (ie traffic crawl) the shifting was a bit harsh. As speed it shifts just fine. When I come to a stop in the drive gear, I get the pattern of surging/rough idle.
The Boost gage wavers a bit as well.
I tend to think its a vacuum problem somewhere.
I should hear from them shortly.
*edit* I called, apparently is the intake manifold gasket, they are removing the blower and I am await a call back.

Maybe I wasn't that far off after all...

Yes, its both the upper and lower intake gaskets. They are sucking in air, causing that vac problem I mentioned.
Good news is no oil or coolant leakage.
Bad news....5 hrs labour...Merry Christmas
