UGH!!! 36,700 miles and now my fual gauge is screwing up

[Matt]

Geez, this stinks... my car was being kinda sluggish so I took it in the shop at 35,850 miles and asked what I could do. They told me to go buy some fuel cleaner, which I did, and add it to an empty tank, which I did, and then fuel up, which I also did. Now guess what happens? The fuel gauge won't move unless I drive for a little bit, then turn the car off and on again... it acts like I didn't even put gas in it... any ideas on what's causing this? If its something like the fuel sensor or something I'll try to get the dealer to replace it since they told me to put in the fuel additive, if not, I'll have to do it myself... hopefully this won't turn into a "meet thing" but if it does, I guess it will be fun to take apart the gas tank (eeewww).

Thanks,
Matt

it sounds like you have the fuel sender error, that some of us have had. There's a TSB on it, so it "shouldn't" cost you anything to get it fixed.
