Idle surges about 300 RPMs up and down while moving.
This is a 2002 Audi A4 1.8T Auto.
The car idles fine even when the transmission is enganged, howerver, when I start moving the car shakes a bit and when the transmission changes gear it shakes again.
I also noticed that once the car is moving the RPM go up and down in a range of about 300 RPMs, during this time the car holds back and then continues.
As you can see this sounds like two different problems, I look forward to read ideas about these two problems.
Thanks in advance.

There was one code, misfire cylinder 3.
This is because the coil on cylinder 3 was not working at all, the coil was replaced and the code cleared.
