for the past 2 tanks of gas ive had i got a CEL at almost exactly half tank and then it goes away around 1/8th tank it has done this on the past 2 tanks of gas....im going to be around half tank tomorrow so well see what happens...

Note: i always use 93 (chevron )

 

Whats Cel are you getting.
Try and get the code to better help you figure out whats causing it.

 

yea if it comes on again tomorrow i was gonna head to autozone before work

 

Even if the light isn't on, since it has come on several times the code will probably be there. Get it checked anyways.

 

anybody know what it might be?

 

maybe its that one you get from not closing the gas cap tight enough?

 

yea tighten as much as possible

The light came on today

 

it's your old car coming back to haunt you for getting another one....

idk man try getting the code and letting us know

 

lol it told me 2 move on

ITS SAYING GOODBYE

 

There's 4 different DTC's on the fuel level sensor.

P0461 Fuel Level Sensor Performance

P0462 Fuel Level Sensor Circuit Low Voltage

P0463 Fuel Level Sensor Circuit High Voltage

P0464 Fuel Level Sensor Circuit Intermittent

 

well i always put 93 in it..should i try a different gas station?

 

you should try getting us the code so we can tell you what the problem might be...

 

i finally got it checked out...they said its a cylinder misfire

 

time for new gas or plugs... are you running a step colder?

 

i have the same code po300 random multiple cylinder misfire wtf is that i have a 2.2 btw it would come on sometimes but tonight i put the cams in and its all the time i think its a bad o2 or something

 

can you give us the specific code? Is it a random misfire or a single cylender misfire?

On these car's it's impossible for a bad O2 to cause a random misfire. If there's an O2 code then it won't allow the P0300 to set.

You just replaced your camshafts... I'm guessing you mean aftermarket cams right? You more than likely need to make timing adjustments for them.

 

This started to happen to my old Cavalier...I never did figure out what the hell it was.

 

i had the code b4 the cam install
