rough idle
My 07 F-150 5.4 has a rough idle during a cold start for about 1 minute. It happens mostly when the weather is chilly or cold. Also after the first start it doesn't do it the rest of the day. Of coarse they can't find anything wrong and tell me there are no updates for anything like that.
Has anyone heard of anything like this?

OP, I don't remember what the sensor is called, but it essentially works like a choke would on a carburator (yes I'm that old). I had a '96 Explorer with a 5.0 that had a similar issue...only when starting "cold". Had the sensor replaced and ran good as new. About ten years ago it was about $50. ...who is "they"?
