I think a 1992 through 2005 Bonnevilles hold about 19 to 20 gallons of fuel. To double check this answer check the owners manual and see if it saids anything on fuel compacity
I have a supercharged 1995 Bonneville and this code has come up quite often. It is a Fuel Trim code. Your fuel is either burning rich or lean.
