.2 volts? I wouldn't worry. A 'normal' charging system is supposed to run between 14-16 volts. These cars suck up electricity. I certainly wouldn't worry about .2 volts. If you want, check your alternator.

Almost any auto parts store will do it for free. Check with an Auto Zone, Advance Auto Parts, or any CSK auto in the area. Yeah its normal for the RPM's to fluctuate. The engine is compensating for the increased load on the system. It should be a momentary fluctuation.
