Cold start jumpy

[jbray1984]

Hey,

I've noticed lately that on cold starts, just after the System Check has finished, if I start moving slowly forward the car seems to jerk/jump. Almost like it's struggling to go forward.
Only happens this once, generally first start of the day. Some days it's fine.
Any idea on what this might be?
Just had a service done like 600k's ago. At a shop.

It's got 63k kms on it, SV6 2008 and Semi-Auto series if that helps.

Mine does that, once I go a few k's it stops..

Think it's anything to worry about?

I had this issue with my VT, stuttering at cold start, turned out to be the fuel pump, 63 thou km seems a bit too soon for this though.
