my fuel gauge is droppig while im driving normal.
it drops about a quarter then comes back up when i come to a stop, but not to its normal position.
does anyone know whats the cause of this?
bad o2 sensor?
help me out.
thanks.

 

When i take sharp turns my fuel gauge will move because the fuel is moving away, or towards the sensor. The sensor is by the fuel pump.

 

you talking about air/fuel, fuel tank, or fuel pressure?

when ever i make a sharp turn or go up hill my gas gauge will drop. like luserkid said just movin away from the sensor

It doesnt even have to be a sharp turn for me, its constantly fluctuating

 

i know what you guys are talking about but my situation is different.
the needle moves everytime i step on the pedal and this is on normal straighaway roads and i know that im slowy losing gas.
also my exhaust is leaking from the cat. could that be the problem?

 

ttt

also. how can you tell if the o2 is bad or not??

Not necessarily. My O2 sensor has been shot since 5 months ago yet there is no CEL. Timing is to spec, all new fuel filter, plugs, wires, etc...etc...etc...from Honda yet my gas mileage on a bone stock D15B7 is at 200-250 per tank. If your gas mileage drops all of a sudden and is totally in the crapper, it's most likely your O2 snesor if nothing else was tampered with or touched (timing).

 

lol. if i down shift and accerlate hard on the freeway, my fuel gauge dips like 1/4 tank, then goes back to the previous position when i'm cruising. i thought civic fuel gauges were just ghetto like that.

 

leaky tank could cause pressure lose which might affect the sensor. I actually don't know if they use a sensor or a float in honda's but either way you have much more serious problems than you gauge moving, you should get the exhaust leak fixed before you get a fire.
