Are you using cruise control while doing this? If so, the clutch switch is not telling the cruise computer that you have pushed the clutch pedal in and as you slow down the cruise computer thinks it needs to accelerate to maintain speed.
It's in a weird spot in the ETK......with the cruise control diagram....
