Re: 2000 Bonneville only getting 10 miles per gallon

So I have a 2000 SE and I'm only getting 8-10 miles per gallon and it misfires. I have put new plugs, new spark plug wires, and all new coil packs and it's still misfiring so bad the car shakes like crazy when parked. Also I can hear what I assume to be the fuel pump humming quite loudly but it goes ...
