Yeah that is my exact problem. It does 2 things unusual
1) Once the car has been sitting overnight and I start it up it apears to be at least a little bit below full, or where it should be. When I start driving it goes right back up.
2) After I use the car a while it will go down a little bit, but when I use it the next time its right back at full, even when I know I have less than a half tank.
If this was the sending unit then it would make sense for it to be stuck at full, but it doesnt make sense at all for it to gradually go down. My only guess is the gauge is bad and somehow it sends the gauge to the wrong spot initially and when the real gas goes down it moves the guage down that much but instead of from 1/2 to 1/4 it would be full to 7/8 or 3/4 (the top 1/4th of the tank lasts a loooong time). So maybe its just the gauge? Ill have to go that test with a voltmeter. Anyone know how much a new gauge will cost?
