i have a 2000 silverado ext. cab, 5.3, 2wd and i've been noticing that sometimes the fuel gauge either jumps up to full when i know its not and it also does the opposite, it goes to empty when i just filled up the tank. it usually does it when i'm at a stop or in park, while i'm driving it slowly goes to where it should be. has anybody else experienced this?
