My lights (dash and headlights) started slightly flickering last night, it's not consistent and happens when warm or cold. The flicker became most noticable when stopped at a light and after five seconds the RPM dropped and a slight vibration started to go along with the flicker. Think these symptoms are related? The only post I found related led me to the alternator (2 years old) or more specifically the voltage regulator there-in. I've checked/cleaned the connectors. Nothing is grounded beyond stock. Ideas?

How far does the RPM drop?

If your alternator is going, the lower RPMs will cause the alternator to produce less power.

If your car idles close to stalling, this will also cause the alternator to produce less power.

Since you're getting a vibration, you could have several problems.
1. Motor mounts shot
2. coil pack going
3. old spark plugs
4. plug wires loose or shot
5. leaking injectors
6. IACV adjusted too low

Well, since I'll be changing the mounts in a day or two that'll answer one question. I'll check on the plugs and wires, though it's a different vibration than leaking injectors produce (i knew that vibration well for a spell). I've never tusseled with the IACV so I'll search on it. It's not close to stalling, just grumpy, kinda like a kid who wanted a pony for christmas but got a sweater.
Oh and RPM drops just below 700 at a light, but takes about 5 sec to do so
