Vehicle make/model = Oldsmobile Alero
Year = 1999
Mileage = 99,040
Engine size = 2.4L
work done prior = step-parent "attempted" to fix the gas gauge,
sticking a wire in to pull the needle over the full notch
tech = jk
question = Battery problem caused all needles in dash to fly rapidly
back and forth, all needles went back to normal, except the gas gauge
needle which stuck over the full notch, it was pulled back over the
notch by step-parent, who thinks he knows all, but now reads quarter tank
off, is there any way to fix this? Or is this permanent because of
other "attempt to fix"?





JK:
Moving the needle back is actually a good trick. We do this all the time, never with a problem.
It is POSSIBLE that cause the gauge to be inaccurate, but unlikely. Unless he really had to force it.
More likely is the battery problem that caused them to all go crazy originally. This is assuming that
the fuel gauge worked correctly to begin with. If you ever noticed that the gauge would jump
around when driving, of one minute says 1/2, the next says 1/4, then a common problem for that is
the level sensor in the tank.
