When you start up, do you wait for the kick down in RPM before going?

If you go within the first 45 seconds of startup without waiting for the kick down in RPM (High Idle Start), it will surge.

There is also another cold surge related to auto transmission warming up, I believe it's the torque converter lock-up, not 100%.

If neither of these apply, consider making a video.
