Sometimes slow auto turns

We have been working on our autonomous sequences and have been having an issues on one of our turns. The robot goes through 5 turning sequences with gyro values. After the second turn, every time the robot needs to turn again it does so at half the speed. We check motor speed values and they are constant through out. Any one have any ideas why this might happen?

From the other thread:

This seem to be the problem. We activated both and it seems to be working much better.

Sorry that I posted in this thread, I thought I was in another thread.[/quote]

Possibly a code issue? Do you have any errors in code when you boot up the FRC driver station to the robot?
