I first noticed a few months ago that my headlights were flickering ever so slightly (most noticebaly at idle, but at all rpms). Then I looked around and realized all of the lights in my car were also flickering. I think the voltage in the electrical system must be fluctuating to cause this. It has gotten progressively worse in the past months. The alternator still charges the battery very well. I had it replaced back in February of this year. Does anyone have any idea waht may be causing this and/or how to fix it? Could ity be a grounding problem of some sort?
Also, today my check engine light spontaneously came on and off while I was in low rpm in 2nd gear. Any thoughts on that? It didn't stay on.
