my gas gauge has gone wacky on me. it reads that i only have a quarter tank left and then when i go to fill it up it wont even take half a tank. and then the gauge doesnt even read the tank as being full. it started out as a smaller margin but now it seems to be getting worse. do all 3rd gens suffer from this? or is it something that is going/has gone out in my car. how do i go about fixing it?

 

i wish, seems like i fill the tank and half an hour later it really IS empty

 

yea they all suffer from this. but usually when the tank is full it goes to 12 like on a clock and when it gets liek half down it starts to bounce around. really nothin you can do unless you want to tear down the gas tank

 

yeah i have a similar problem with my gas gauge in m 85 trans am...once it gets down around half a tank it just dances...and when i fill it it goes passed the full mark...i just keep track of what miliage i filled it and judge by milage when to gas up...good to hear i am not the only one

 

The sending unit in your tank is probably on it's way out. You should check that your grounding points are all good before replacing anything.
