What could cause rough idle in cold weather on a Ford Escape?

[Nicko]

Anyone else dealing with rough idle when it's cold? My Escape starts acting weird when it’s chilly out, especially on cold mornings. It shakes like it’s had one too many espressos. Any idea what’s causing this? Could it be spark plugs, or is it something else? Trying to avoid a trip to the mechanic if I can.
