Anyone experience TB return spring failure?

Or what ever they call the coil/spring that holds the throttle shut....

When I start the engine the TB blades start to open on its own and the RPM's start to rise, until I panic and shut the car off. When the engine is off the TB stays closed, as normal. I checked the IAC valve voltage (normal) and cleaned it (no change). No throttle cable kinks and the plastic/coil peace seems to be in good shape...

I don't think a vacuum leak would make the TB move on it's own, would it?

disconnect the cruise control cable and see if it still does it.

Don't forget there's two springs there. Very unlikely they both broke.

X2 that would be the only thing that would open it..

Cruise control. Never thought about that....
Thanks for the tip. I'll disconnect the cc and report back.
