so i have noticed for few months that the fuel gauge needle sometimes goes down a little bit and than comes back to the original reading..its only a minor drop but can be noticeable. And it usually happen when driving. and it doesn't matter what grades/octane of fuel i use. any one has any idea..???

 

Does it happen when you are turning, going straight, accelerating...?

 

hmmmm def not by turning ( i think) . yes for going straight and yes for accelerating..it also happens when i just crusing on the highway

 

it's your fuel level sensor probably.
it's like a floating device in your gas tank attached to your fuel pump assembly.

take it out and take a look if you really want to fix it.

 

ya thats what i was thinking too..is it expensive to change and labor too?
