of acceleration. It's not a miss, not a buck. Just feels like the motor is being slightly held back.

I've put in new plugs, checked the boots, they look good. Cleaned and Used dielectric grease on all electrical connections and checked the wires and did a visual check on the intake hoses.

Before I go down the POS / Coil route..what do you guys think about the Throttle Position Sensor being bad rather than the POS / Coils?

Reason I'm leaning this way is that it happens at any speed but only at neutral throttle or light deceleration. Under full or moderate acceleration / boost it's smooth and solid.

Thoughts?

Did you find out what it was? My A8 is doing the same thing.

I would expect ignition issues to be worse with load, i.e., on acceleration and high boost. The steady cruising problem sounds like a fuel issue, either fuel pressure regulator or fuel injectors.

I was thinking throttle position sensor because as it turns out, mine doesn't do it when the cruise is set.
