We just had one of our M9960's throw an Error -3. When we started it up this AM, it went into a pretty high idle (1300rpm), and as soon as I touched the throttle it went to low idle and coded. After it posted the code, there was no throttle response from either the hand throttle lever or the foot control. Anyone have any experience with this?

Looking to see if there is a simple fix before I contact the dealer later this AM. Thanks!

It's past late morning...

Anxious to hear what the dealer said.
