Well if this didn't happen before you worked on it, I would venture to say that you have a vacuum line not connected.

when I had this problem it turned out to be the idle control solenoid which is on the older cars that needs to be cleaned or replaced or it could be your throttle position sensor on a newer sat like my 2001 Saturn sc2 that's what my problem was the throttle position sensor but I think it's more likely like the other guy was saying could be your vacuum line that's missing somewhere.
