Hi Guys. New to the forum.

My '06 GT was running very rough. As if it wasn't firing on all 8 cylinders. I dropped it off for a check at my local repair and they told me that it was now running OK, but a diagnostic showed that a solenoid that controls Cam timing had been stuck. The tech said that it might, or might not happen again. I am not familiar with this situation, so I was wondering if this solenoid should be replaced. Any of you techs out there have an opinion?

Thanks.
