This is weird. Several months ago, the gas gauge on my '92 940T stopped working. Without power it sat at 0 and with power sat at full. Took a road trip last week and after filling up once, the gauge decided to it wanted to read empty, so the needle fell all the way to zero. Then went back up and fell again. Repeated this over and over. Got to where I was going and while I was there it stayed full, but when I got back out on the highway, it started goign back and forth again. Since returning home it decided the stick about half full for a few days and now reads full again. Any idea what is going on? Wiring problem? Problem in the tank? I assume it;s not really going to hurt anyting, but it sure is annoying.

Any help is appreciated.

Thanks,
Sam
