Old Styleeee Coil Packs

[dooahhdoo]

I need to diagnose rough running on my scoob. Its not just on boost it seems to be all through the rev range (only revved to 3.5K due to running in).

I found a coil pack that wasn't sparking so managed to get a replacement. It ran a little better but has started misfiring again so I want to change them all to see what it could be next (Lambda, boost solenoid, MAF etc). I feel hard of spending £200 notes as it may not even be the coil packs but they are chief suspect no1 at the moment.
