These cars tend to run well on NGK spark plugs. Those E3 plugs just look like a marketing gimmick. The spark is only going to go to one of the 3 electrodes, the other 2 are simply in the way of flame propagation. I can't guarantee that these are the cause, but they could certainly contribute.

Your misfires are on cyls 1/3, which share a cam. You also mention a cam code. Might want to double check the timing.

It never hurts to check grounds for a clean connection.
