Hello everyone, I have read several threads about problems with erratic fuel gauges, but my problem is slightly different. Like the others, the needle on the gauge jumps between full and empty, but unlike any that i've read, the needle stops and begins working normally as soon as the car is put in drive and begins moving. I just wanted to know if anyone thinks the sending unit is still the likely culprit in this situation? or does anyone think something else is the problem since the problem fixes itself once moving? Any help is much appreciated!
