Why does my 2004 Chevy Impala run like crap when it gets down to 1/4 tank of gas?

Mr. D

This happens to my 2004 Imapla as well as my girlfriends 2005 Impala. When the fuel gets just above 1/4 tank, it hesitates and runs like crap. Why is this. It should still have plenty of gas at 1/4 tank. Thanks.
Fuel filter was changed a couple weeks ago along with the vapor cylanoid.


sounds like a fuel pressure/pickup issue, it may be as simple as needing a new fuel filter - that's where I'd start. If you plan to change it yourself don't forget to depressuize the fuel system first.
