Hi Shane, I don't know if this type of fault will show up on a scope or not. ?? Perhaps some of the More Qualified Scope guys could answer that one, ( I use the scope very basically ) I would think it could if you know what your looking for and have a decent scope. ??

If the Coil pack hasn't got a decent name stamped on it then I would just try a new Delphi one, I Used to Bin NGK plugs at every opportunity due to lots of problems but I haven't had many problems with them recently. ( But I Would still try a set of Bosch ones if the coil pack doesn't cure it.

It Will be interesting to See What BBA say about your ECU too.
