My Accord sometimes sticks on high revvs, around 2000-3500 and won't
come down. And when I step on the gas to bring the choke off it revs
higher and stays there as if in correlation to how much gas I gave it.
I have had it checked by Honda Techs, he was sure that it was the
vacuum box on the firewall so I replaced it, didn't work. He also
cleaned out the carbeurator without removing it, which seemed to help a
little. The problem also seems to be only in cold weather. I am
concerned that I am doing damage by driving it this way, because
sometimes I have to throw it into gear (auto) and drive it this way.
HELP!
