Cold start erratic idle help

[97SportOHV]

I've cleaned the TB, mass flow air sensor and replaced the idle air control valve still doing it now I'm thinking a vacuum leak? intake manifold gasket? When it warms up it idles a lot better.

I'd be replacing the intake manifold gaskets. Sounds like they're leaking slightly. Especially when the engine is cold. If it was a vacuum leak(s) elsewhere it wouldn't make as much difference once the engine warms.

Is that a check engine light I see?

No check engine light that was door ajar and seat belt, never had a check engine light on.
