2003 Honda Civic 4 cyl Two Wheel Drive Automatic 134000 miles
After having the timing belt, water pump, spark plugs and air filter changed, my 2003 Civic is idling between 500-750 rpm and will shutter every couple of seconds. The battery voltage will drop to 12.3 volts when accelerating and at idle and returns to 14.2 when gliding. This has happened 1st day of driving after the above repairs and the 3rd day. Day 2 the voltage stayed at 14.2.
Is this an alternator or voltage regulator problem? Also, is it a DYI job to change just the voltage regulator or are the alternator and regulator sold together?
