I have a 2004 impala.17000 mi. 3.8 4 door .the fuel gauge started dropping to empty,low fuel light comes on and the overhead computer display will show -e- in the screen for my fuel range. then it will go back to working like it should.this happened twice in about 20 min. it has done this about 10 times? any ideas anyone. this car has been a great car,we have never had any other dash problems like i've seen on here. the trans does shift alittle hard every now and then ?
