ps
could it be your distribitor cap
if theres a lot of mileage on your car, the coil in the distribitor could be burned out
take the distribitor off the car, then dismantle it,as far as i know its 3 bolts holding it together
you will see a copper unit,= thats the coil,
look for scorch marks, if there is thats your problem
unfortunitly, its a common problem on old hondas, its just wear and tear
if it is the problem, just recondition it,
the coil will cost about 90 euros, what ever thats in sterling but takes 5 mins to fix
i would check that anyway next,
let me know mate
