Throttle updates?

    Ok, still going through my shakedown questions on the Yukon. This one is around the throttle response. I've noticed that the response is a little weird/touchy off idle. The pedal itself is pretty stiff, and just off idle, like when starting from a stop, it's like there's a dip in the response. Push the pedal a little, get a little RPM rise in response, push a little more, no change in idle, push further, the RPM jumps and you're off.

    If I understand correctly my 2003 was the first year of fly-by-wire, and so I'm wondering if there are any updates that can be performed?

    I would say call your local dealership and ask them if there are any software updates that GM has put out.
