[quote name='InstructorPiggy' post='56250' date='Dec 22 2009, 07:51 PM']Does it miss at idle???
If so, remove the leads one at a time as its running, (then replace obviously!) and see which one makes NO difference to the misfire...then turn engine off and inspect plug...see what colour it is, and look VERY carefully at the ceramic...may have the tiniest of cracks!
what make of plugs did you use?
also, if it does miss at idle...take it to the darkest place possible, lift bonnet, turn all lights off and look out for any little lightening jumps from the Ht leads/coil to the engine
Engine does not misfire on tickover,have removed plugs one by one all nice colour no obvious cracks on ceramic,could i have a dud spark plug
