Oh.. ok.. here goes then.
Test coils via procedure in Techinfo with a multimeter
Check that a wire isn't touching the O2 sensor wiring.
Further in..since you'd be doing plugs and wires.. (no Bosch on plugs BTW, our cars eat them for breakfast in our experience) you might want to clean the TB and sensors.
Those are the standard items. Further along..and not necessarily relating to your symptons, we often suggest cleaning the battery cable terminals and looking under the boots for corrosion.
