Usually found to be the driver output of the ECU at fault.
I've done a fair few,
good news is it's about the cheapest ECU to get repaired.
Fault codes are cyl miss fire,
multiple cyl miss fire
,etc,
etc.
And usually the coil pack get's the blame,
Only way to be sure is with an ignition trace on a 'scope.
Or send off the ECU for testing.
