For some reason my fuel guage stopped reading corectly. It seems it is stuck in "full" position, even after driving 150 Miles. Sometimes it goes from full to nearly empty in less then 200 miles.

Anybody else had run into this problem. any suggestions.

Never mind. I found the solution. just pour fuel system cleaner in the tank. Then let it sit for few days to remove the gunk built up on the level flowting units in the tank.
It seems to have helped my problem.

Glad that fixed it.
These cars are know for that problem.
