Rattling Noise From Left Side Of Dash
 

When I put a load on the motor I hear a rattle from the guages on the left side of the dash. I was curious to know if the economy guage will do that. It seems when the guage is at either end of its range ther is no rattle, but in the middle of its range there is. Has anyone else experienced this before? If it is the guage, could it be tightend or should it be replaced?
