8v uneven pick up on throttle

My dear old 2008 8v is running a bit rough.

She starts fine, but dies with any throttle at all until warmed up for a minute or so. When pulling away, there's a bit of throttle movement before the lump responds. It then feels like it is running one one until there's a tiny bit more throttle, and then the thing surges into life. This really uneven pickup continues on very small throttle openings, but feels a lot more normal with a bit more throttle.

What do you think?

Check/adjust throttle cable play. Then perform a throttle body balance.

Yup, give it a tune up and if that doesn’t work we’ll dig further.
