td5 missfire with a difference

ive got a strange missfire ....it dont missfire under load ..or at idle ...only time i can get it to miss is when brakeing and slowing down once the car has come to a full stop ie no wheel speed input the ruff / miss fire stops and it runs so sweet , it isnt to bad and not noticable ..but ive noticed it and wana try and sort it ... im thinking 2 possibilitys ..1 the clutch switch isnt telling the ecu ive put me hoof on it ....or the brake switch isnt ....any one have any expirience of the same kinda fault ...


sorry forgot to add is a 2002 disco

could it be a cable that when you are braking moves forward due to the braking and shorts but when staionary it swings back and when accelerating it is being forced away ??? Bit of a long shot i know
