What type(s) of spark plug wires, and plugs are installed?

Thanks for the explanation. That helps me rule out the O2 sensor.
The EHA is suspect to me because that is the newest part that was swapped in (prior to the ICU) and it was used. Is it possible that the EHA is the culprit or that is set too lean?
Regarding the spark plugs and wires, It is raining but I am 99% sure that the spark plugs are NGK BP5ES (they could be BP6ES). The wires are the correct Bosch resistor wires. I can get the numbers of the wires later today.
