Problem with 86 F250

I just bought a 86 F250 a few weeks ago & when I start it cold it idles at about 2k for 10-15 mins. It idles real rough until it warms up & will stall if I let the clutch out. Once it's warm the rpm's drop to about 1k & it runs pretty smooth. Does anyone know what this could be?

Thanks

Mark

Is it fuel injected? Try tightening the intake manifold and plenum bolts.
