Eratic Idling

I have a 2004 Honda Odyssey that idles eratically when cold. Any suggstions?

too many things could cause this. we need some history like miles what have you done lately in repairs. what engine do you have. I bet if you take it to p—b--- they will fix it for $ 1000.00

Had a similar thing happen this morning with my 2000 Accord. Someone suggested a possible vacuum leak associated with the idler air control motor. Haven’t had a chance to verify yet, but other posts I’ve read regarding erratic idling have made the vacuum leak suggestion too. Good luck.
