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.
