My 2002 750ie does the exact same thing, assuming that by "cold without throttle input" you do mean with the fast-idle lever on.My 2002 620ie starts cold without throttle input, but when it has been running for awhile I need to give it gas after shutting it off for a few minutes. Is this normal?
ya i have the same problem on a 750,
My 02 750 needs the lever to start initially, even when the temperature outside is 90 degrees.
