I need some help/advice with two issues I am currently having with my 2003Civic w/1.7 L 4 cylinder with approx 45k miles:

1. I received my last service from my Dealer. They stated that the lower control arm bushings need replaced. That is expensive work to have a dealaer do (Approx 400). Are the bushings the same as the ball joints? Second, has anyone done this replacement and is it pretty simple for a medium experienced person to do?

2. Not all the time, but occassionaly, when starting off at say a light, I hit the gas and get a hesitation in response from engine. I think something ignition or either fuel pump or fuel filter. Anyone experience such an issue? Liek I said, not all the time, just occassionally, like twice a week and I drive approx 45 miles a day.

Thanks for anyone's help.
