It looks like a misfire, you can see the lambda go erratic at the same time.  It is heading very rich just before it starts to misfire though - have you tried making leaner in that area?

Are they genuine coils or a good quality branded replacement like Bosch?  I have see some very poor performing clones of the Toyota coils.

Bosch 0986AG0502 is the one I have used before but that was the 2ZZ one which I think is slightly different mount location.  These gave better life than the factory Denso ones when I was involved in the Toyota racing series.  Looks like 1ZZ part is 0986AG0503

I've also had good luck with NGK coils for other engines so they are possibly worth looking at.
