I have a 2004 cavalier, I've had it for a year and couple of months. for the past month or so, my gas needle will do this randomly:
The needle will very slowly go all the way down to E (empty) and my "Check Guages" light comes on. then the light will turn off, and the needle will go up to the correct level.
It usually does it more than once when it happens. It may do this once or twice a day, or go a week without doing it.
anyone know what would cause this or how to make it stop?
These are the mods I have done to my car:
Weapon R intake, B&M shiftplus, and a chrome dash cluster bezel.
I don't think any of my mods would have caused this to start happening. I will remove all of this when I go to the dealer ship for them to check it out sometime this week.
Um. the fuel moves in the tank. So if you are going up a steep incline or downgrade the fuel level will change then go back to normal.
If that's not what is happening take the car to the dealer to have it checked out. It should be under warranty.
My Car
Same thing happened to my car ('00 Cavi)... it happened about 10 times over the time frame of 3 days, then got better all by itself.
I talked to my neighbor who is a tow truck driver and he said this:
If your tank was at one time less then 1/8 of a tank your float may have gotten out-of-whack, so now it sometimes "sinks" (or at least the computer thinks it is) then it realizes this cant be and basically runs its own little system check on that part of the computer.
He said I probly went over a bump fast or did something that re-aligned whatever mechanism of my float may have gotten screwed up, and thats why mine seamed to fix itself.
I have no idea if thats what happened to my car or not, but he said that was a possability. No idea what you could do to fix it if that the case. Maybe just wait. Otherwise a dealer would probably have to calibrate it or whatever, and i know any fuel system work is expensive unless you got warrenty.
