"lumpy cam"...normal and many high-performance cars do it.

Normal, atleast on every S4 I've ridden in

Also, the 2.7T is a 90° V6 -- not the best design for a smooth six.

I have been playing with VAG and when I felt the rough idle, VAG indicated several misfires. The misfires were not consistent. The ECU monitors for misfires for a fixed period (like 30 seconds), then resets the count and start over. If the ECU counts too many misfires during a particular period, it sets a code. I did not get a code, but did get between 4 and 8 misfires during the monitoring periods I was watching.

I'm not sure why I'm getting misfires, but I'm guessing this is what others are feeling as well.

On cold starts, misfires are common till the plugs come up to temp...

At least for me, happens even when car is fully warmed

Every 12V 2.8 does the same.

will have to pay more attention next time. My 996 also does it.
