Re: 2000 Bonneville only getting 10 miles per gallon
Ran a code on it and it's got random misfires. So I already changed plugs, plug wires, coil packs. What else can cause a misfire?

Re: 2000 Bonneville only getting 10 miles per gallon
Firing order is correct, car is at optimal temperature. I just filled it up and I'm down to 7 mpg. I have been meaning to change the fuel filter which has never been changed is it possible that the fuel filter is all gunked up and causing problems? And when I start it it smells like straight gas.

Coolant is all good, I'm planning on just changing all my injectors to see if that helps. And now a new problem is my AC bearing starts whining when I turn too sharp. It's just one thing after another with this car.

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 ...
