The truck won't stay running when the motor is cold. It runs fine after it warms up.

Both.

...Or move to a warmer climate. :)

When mine was doing it, 52 degrees was the magic number. Above 52, it idled fine. Below 52 at night? Rolling idle in the morning. At all times, it idled around 500RPMs when warm.

After the lower intake manifold gasket swap? Idled at 600 ever since, no cold start issues (well, one lately, but it's the IAC, not the gaskets)
