Hello,
2000 LS, 3.8L, roughly 125K miles
I am having a problem with the fuel guage. It started about three weeks ago. When it gets around 1/2 tank or below, it acts very erratically. It will drop to nearly empty, then go back up to 1/2. then it may drop to 1/4, stay there for awhile, then go up (or down). It triggers the low fuel message when it drops low enough. It tends to really only move up or down while the car is moving.
It seems to act correctly when it is full to a little more than 1/2 tank.
Any ideas?
