> My car starts up fine but immediately idles roughly and will stall if you

> 
> This is both in warm and cold start conditions.
> After about 1 minute the problem resolves and idles normally.  There is no
> smoke from the tailpipe on startup.  Briefly I visually checked the
> vacuum lines and they look intact. No fault codes or check engine light.
