Possible start of electrical part failure?
Hi, I have noticed the car recently starting to give subtle signs of impending issues.
2005 Impala LS 3.8
3 or 4 days ago, I noticed the gauges went haywire for a few seconds as I was pulling out of a parking lot after work. Returned to working fine.
yesterday, I noticed the idle rpm is sometimes a little higher than normal (1100 rpm). I noticed this only because during coast at low speeds, I felt the car was pushing me faster than usual (that's how I noticed it at first).
This morning I started the car in my garage and the headlights and gauge lights were slowly flickering normal intensity to low intensity and back and forth for about 15 seconds. During this, the idle was acting a little erratically, slowly climbing to around 1600 rpm or so before slowly dropping back to 1100 (again higher than usual idle rpm).
Any obvious wires touching hot parts to look for first? What can I check?
There is no CEL at the moment. and no messages in the message center.
Any ideas? I googled a bit but didn't find anything. The BCM wouldn't control idle would it? Are there any notorious ground points on this vehicle that would need cleaning?
