Ok, this problem is driving me and my friend nuts!
I went out on my break and decided to pay attention to the idle and see exactly what happens.
It is very bizzare to me. It idles at 500 rpm, them all on it's own hops up to 2,000 rpms. It did it on it's own. I watched this for about 10-15 minutes and it kept doing the same thing. A few times it dropped below 500 rpm's and the battery light came on a couple of times.
This is confusing me. Do I have more then 1 problem going on here? Do I also need another battery? I bought this battery back in May of 2000. Also, I usually have the heat on high while it idles (I have a remote starter so my car can be warm by the time I get outside to it, 12 degrees is way too cold for me) so I turned it on low and it didn't die this time. What about my alternator? That was replaced way back when also. I do have an extra alternator so if that should be replaced I have one on hand.
Any ideas?
Thanks!
