These are prone to coil pack failure,
and a new pack "sometimes" fixes it,
But often the failed coil pack can damage the ECU,
Only way to know is by fitting a new coil and seeing "IF" the same miss fire code returns,
A sure sign the ECU has gone too.
So some form of scanner would be of use to you.
They are easy enough to use,
Understanding what the show really does take an understanding of the vehicle systems.
Miss understanding leads to costly parts not needed .
Codes must be treated as a GUIDE,
Not as instructions to replace anything.
