I have a 96 Legacy station wagon 2.2 that has a rough idle only when stopped and in Drive. It purrs like a kitten in Park and does fine everywhere else. I've adjusted the idle screw more than once and checked all electrical connections; it only has 70,000 miles. I noticed when I turn on any electrical device in the car at night that the dash board lights dim a little even when driving. I measured the Volts and it is 14.70 in neutral and 14.20 in drive when parked. I'm new to this type of Subaru issue. Any ideas, thoughts and suggestions would be welcome and I'm sure helpful.
