Idles great. Sounds great. Starts great. Cruises great. Accelerates like it has a normally aspirated four cylinder. I expect a 320 to accelerate like a solid fuel missile.

Since I don't get the car home until next week I am probably jumping the gun with this thread since I hanve not yet so much as pulled codes and done a basic inspection.

Given that this car has variable length intake runners and cam timing manipulation, I thought maybe someone knew of a common trouble spot that could cause this. Especially since the engine is used in so many other models as well.
