A friend of mine has a '97 Lumina. 3100 engine, 110k on it. She's been having some odd problems with it lately.
These are all "occasional" problems. Open the door and sometimes it'll take about 10 seconds for the dome light to pop on. The ABS light will come on randomly... step on the brake and the light goes off. The clock on the radio randomly resets to 11:00. If she hits a hard bump (railroad tracks for example) the car will simply die.. it'll restart like nothing happened. I think random idiot lights will come on and go off, many at a time.
Awhile ago, she said something about how it would die if you put it in drive, but it would run fine in reverse. I think that was quite some time ago, but it was something that happened for a few days, then never happened again. Probably not related.
The battery and alternator are new within the past few years. The terminals and all grounds are tight and clean. The aux post is tight. Any idea what it could be?
