problem with my 7G...car shutting off
the car seems to shut off on me. I don't think it's stalling, just shutting off. Or maybe it is stalling. Occassionally when I come to a light or a stop sign the rpms will drop and fluctuate arouns 500 or so. I have had the car shut off around the same times too. And When I start the car back up sometimes I have lost the settings for my radio. At other times I will have to reset the clock, also the CEL I have for EGR valve malfunction will disappear. This morning for example I left my car running at Dunkin Donuts while I ran in for about 10 minutes. I came back out and the car was not running. I went to disarm the alarm since the car was running with the remote starter, and the alarm wouldn't disarm, when I opened the door with the key and got in I noticed the light on the dash for the door being open was dim. I attempted to start the car once and no luck, I attempted a 2nd time and the car started right up.
I dunno if this problem is related to the cold or what. The only thing I have done to the car lately was I installed a set of HIDS a few months ago. And before that I had a problem where I blew the fuse under the hood for the radio, and for the dome light and the clock and whatever else is on that one. I replaced that fuse and that hasn't been an issue.
Whatcha guys think battery? I am not sure how old it is. Or maybe alternator?
any help would be greatly appreciated.
