I have a misfire under boost, had it before & I fitted a set of genuine (brand new) plug leads, seems the same symptoms to me. The new leads have done appx 5000 miles.
My car has a MSD Blaster uprated coil pack. SO, would the blaster make the standard leads fail early? Or are my plugs tired? There no misfire when I rev it up at idle, its only under load/boost.
Without breaking the bank, who makes a good set of leads that can handle the MSD? I know Magnicor make 'thick' ones, at the mo they're out of my price range.
