MIKELABZ Posted July 7, 2004 Report Share Posted July 7, 2004 who put the battery in? Quote Link to comment Share on other sites More sharing options...
supreme_style21 Posted July 7, 2004 Report Share Posted July 7, 2004 .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. Quote Link to comment Share on other sites More sharing options...

syknesss Posted July 7, 2004 Author Report Share Posted July 7, 2004 how do i check the alternator Quote Link to comment Share on other sites More sharing options...
supreme_style21 Posted July 7, 2004 Report Share Posted July 7, 2004 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.

MIKELABZ Posted July 7, 2004 Report Share Posted July 7, 2004 that could be due to an EGR valve. Quote Link to comment Share on other sites More sharing options...
