Throttle Hang..
it is on the main page of the Contour.org FAQ's....
Install the TH fix, and you will see little to no hang, anymore.
simple, under 30 cents, and painless.
For more info, search the term "throttle hang" in thr troubleshooting forums.
This also is a "most of the time" fix for the moosing that you may or may not have occuring periodically.
I say most of the time because I have read of one user with the TH fix installed who still received the moose once in a while... but no others.
