"revving" when starting
my girlfriend has a '02 2500 5-spd with a 24v cummins. her truck revs to 1200 or 1300 rpm's when it starts with no foot on the pedal then idles down to normal. I haven't dealt with 24 valvers as much as the 12-valve ones and was just wondering if this is a sign of something wrong(injection pump dying, apps, sensors, etc.....). Thanks for any help and its greatly appreciated
EDIT: also as far asi know there arent any codes because the check engine light isnt on

There could still be codes even though the CEL is not on.
You can check them without a code reader on the '01 and newer trucks by cycling the key to on-off-on-off-on quickly (without starting the engine!) and read the codes in the odometer window.
