Hey guys and gals, I'm new on here and I have a question for you. My fuel gauge has been acting up lately and has been going up and down a lot. I have no idea what the problem is. The car could be on a perfectly flat surface and go all the way down and the low fuel message comes up on the display. I thought I'd ask you W body guys since I am not as knowledgeable on Ws. I could probably search but I am too lazy.
Any input is greatly appreciated before I try strolling down to the dealer and chucking my money down the toilet for them to just "take a look at it".
Forgot to mention I have an 01 Impala LS w/L36
