let my 540i sit for a week or two, took it out and its real slow for the rpms to come down to idle, and has a wondering idle. checked for any vac leaks. didn't find any so i unpluged the IAC and it idles high but it revs down normal now. also feels a bit better then it did even before it started acting up. Does this sound like a bad IAC? its a 94 also
