Could the new codes be due to the possible faulty igniter?

The plot thickens.. I pulled the plugs, they are all pretty bad. The strange thing was the first 4 plugs were Bosch Platinum FR7DP. The last 2 were Denso PK20R11.. Why? Why would the last 2 be different? Are they a hotter burning plug?
If the a/f is very lean, the spark may not ignite consistently. However, when the spark doesn't ignite, the exhaust is very rich (because no fuel was burned). Makes sense?
The plugs should not be different. Go with oem platinum plugs, or NGK 6097s.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
