well wonderd how long it would take as been misfiring for abit now sometimes but last night on the motorway, put my toe down abit to over take and bloody thing wouldnt go after, engine management light stayed on, misfired like a beaut as i drove 15mph in safe mode to my mates house, just waiting for my dad to pop over 2mw with his comp and plug it in to see what the fault code is but im guessing its coil pack now and not plugs (dammit)
