Why the rough idle on ford explorer for first 2 minutes when cold?

Could be a coolant temp sensor not telling the computer to open up the idle air valve. More likely, the truck just needs a tune up and you only notice it when it’s cold.

Yeah Greasy Jack I do notice it when cold. Plugs are new and no vacume leaks. Filters new too, yet all plug wires not replaced. Wires all seem good. I don’t see or feel short.

Where is idle air valve and how do I check it. No check light is on.
