I checked the coolant and it is okay. The battery is a Honda battery
replaced by the Honda dealer in December, 2006, so I doubt that could
be a problem. I've done a little research and the things that come up
are: throttle body & the EGR thing and the main relay. As I said
before the main relay was replaced last year. Could a dirty throttle
body cause both the hesitation and the starting problem? Why would
both things happen at once?

Thanks, Bridget.
