Engine problem

[MWOOLY10]

To update this..Didnt get new leads as they kept sending the garage the wrong ones..But they changed my plugs as the others were burnt out completely as all the carbon tip had disappeared

Used it to go to london last night got about 120 miles down the motorway and it bloodly started again,but not as bad...Stopped at a garage for a few minutes started her up again and it was fine again for a while..had too stop a couple more times on the way home..but got me there and back at least

Just wondering now wether it is a lead or is it something to do with the engine management system??

Any thoughts anyone
