Ooh, I'd get it along to an accredited Honda mechanic - check the yellow pages. He'll be in a better position to advise you.Although, my Mum's Corsa lost power going up slopes and hills and would conk out. Dealer found nothing wrong but the problem persisted. I changed the HT leads, the distributor cap (slight crack in it) the plugs (about 5 years old) and the rotor arm (in the distributor) and it goes like a bomb again.
