My girlfriend recently bought an automatic 97 cx hatchback. Great car. The only things that are slightly off with the kar are paint (no surprise) and the fact that while driving the needle on her fuel gauge wanders a bit all the time. It wanders both up and down slowly for a value of no more than but most often less than 1/4 tank.

Suggestions??

 

Oh and btw for those that kno me or hav been in my other threads. Ill be starting a DB7 build thread soon. Naturally thats gonna go in the teggy section so im saying it here so noone misses it. Ill be putting the link for it in all my threads wen i make it.

 

It's a old Honda, it's going to do that. Mine does too.

It's awesome when you forget your car does that and your parked on an incline (driveway or something), and you think you gotta get gas. Then when you pull onto the street and drive for a quarter mile or so, it shoots back up to 1/4 tank or something. Score!

 

Hahahahaha!! Epic, ok i see thanks .mattyz

 

Yeah mine does the same thing...no big deal.

 

i noticed when i did my crv gauge cluster swap. mine fluctuates no where near as much i just think the civic cluster is just very inaccurate

 

Prolly yea... Gonna swap the cluster eventually anywayz lol

 

Eh, all vehicles do that to an extent. Really though, the reason why the fuel gauges fluctuate so much in these cars like when taking turns is either because of a lack of baffles in the tank or due to the shape of these fuel tanks which lend themselves to lots of fluctuation when making turns. But the up hill down hill thing with the tank showing more or less fuel, all cars do that.

 

lol well the fuel gauge in my girls hatch fluctuates all the time lol not just while turning but while going in a straight line too lol

 

mine does that too when i take off from a light in a straight line it gos down about a quarter. and just for the record my g body cutlass does the same its nothing to worry
about

 

Do you think this is a problem with the gauges themselves or the actual tank level sensor (or however it reads gas level) Like say...if you put a digital s2k cluster in would the gas levels bounce because they are just getting a shitty reading before it even gets to the cluster?

 

Mine wanders once it's under 1/4 tank. The last 1/3 of the tank or so features a rapidly dropping needle anyway, so I'm paranoid and fill up at 50%.

 

I guess this is the real reason. It's not that the civic cluster is accurate, it's just that it responds to movement of fuel in the tank too quickly so when you make it turn, it adjusts itself a little too quickly.

 

I want to look into the fuel tanks. fleabag said something that could make sense that these tanks have a lack of baffles. Also thbx59 made a good point that it could just start happening wen it gets to a certain level.
