issue with code

I am having issues with some code. i am trying to get a velocity pid running for two motors. a problem i am having is for some reason analog pin zero seems to run one of the motors even though i am not reading the value or using it at all. i have used timerone.h on that pin to make a pwm signal. is there anyway that timerone is hanging around on the chip? i cannot seem to get rid of this issue.

Post the code then we stand a chance of seeing what is wrong.

i found the problem

buried inside some of my comments was a line that was uncommented
causing the value to be read and written
