My Rio doesn't excellerate and is idling poorly. I think I need to replace the fuel filter, but don't know how. I'm not even sure where it is located. Its not mentioned in the owners manuel! Any suggestions?

it's underneath the car, near the rear on right hand side (as you look at front)
Remove one screw, and push in the release tabs on the 3 fuel pipes.
