I will venture a guess:
1 - you had your AC on
2 - The AC compressor was disenganged (cabin was cold & AC cycles on/off)
3 - when the ECU turns the AC compressor back on, it bumps up the throttle to keep the RPMs from dropping
4 - it happened at the only time you would really notice it (creeping into a parking space)
