ni antony
thanks for the reply, found it to be a dodgy ht lead for some reason it must have been sparking out where it fits on the dissy cap and become stuck evening trying to pull it out it snapped of.
so it had replaced phase sensor, rotor arm, cap, leads and a coil, as this was found to be givin a spark 1 min and not the other.
so fingers crossed it will be ok now

thanks
