NM8SHUN,
Those lights and behavior are exactly what I got when I recently changed the oil in my '06 M Roadster. Different engine, I know, but in my case it was that I forgot to plug in my throttle valve switch that sits right on top of the oil filter after disconnecting it to take the filter out. I think your "equivalent" idle regulating valve is on the intake manifold and may have become loose or undone (see realoem.com for your car under engine and then intake manifold system, items 7 and 8).
Hope this helps.
