Low speed lean surging
My new C6 seems to have a slight surge at lower RPM (between 1000 and 2000). It nearly goes away when the engine comes up to temp, but I can still feel it slightly. Anyone else notice this? Can it be "tuned" out?

mine was resolved when they reduced the a/c pressure to the new 1.1lbs setting.
it is also possible your maf posts are contaminated. a carefully cleaning may fix it, good luck getting pat the screen and not breaking one of the resistors.
