Only when first stated. What should I look at?

If it's only on cold starts, it's likely a leaky injector. But start by changing all of the plugs, which should be done every 20k regardless.

Edit: never mind the plugs, they were just done. You could try moving the coils.

Yup, agree with the other two. Likely leaky injectors.
