I have the Pro Flight pedals (silver ones) and when I slide my left foot to the max extension on the left, the power light surges and throws off all my yaw(s).  I popped out into the Windows device tester for it and it is now around 70% left pressure on the rudder assembly without even touching it.    
Rebooting resets it but as soon as I go left.....fzzzzzt....short and then makes my yaw all whackey.  Anyone seen this?  I can't find diddly on this specific issue.   
Any help would be appreciated.  If anyone can help me, this forum can.
