Sounds like it could be a faulty DIS pack....

Sounds like a failing DIS pack.

Ignition faults like plugs, lead and DIS pack don't show fault codes.

I've seen pattern DIS packs become available recently.

OEM Bosch replacements are around £70 on Ebay. Vx Bosch ones from dealer are something like £120.

Mind you these look promising at £52, but make sure you get the right one for your car there are 3 types.
