I had the same thing a few months back Alan and it was just that one off the leads had come loose
check there all pushed in right first before you replace any
Turned out to be lead failure lads. disconnected them to clean contatcs and opne just came apart in the coil pack . So now it looks like i need a coil pack and replacment lead. Or wont be heading anywhere. Anybody got some to spare. will pick them up.
Got sorted so just tyres to do in d morning. Big thans to jamie for digging me out of a hole ill be sure to get parts when needed again. And cheers to ian and carlo. See ya tomorrow lads.
