After refering my maintenance and service manual many time over and performing all tasks mentioned that would effect codes 41 and 43. Tried manual code erasure with no luck. Both the old and the NEW WT sensor resitance readings fall outside the limits of 985-1015 ohms according to my manual. The old reads 1034 and the new right out of the box reads 1021. Did I receive a faulty new sensor? 
After chilling the old sensor in the fridge, I then installed it and I got a code 11 for system OK. But after starting it, it gave me the check engine light again.
Another scenerio I had was since the P/N of the upgrade kit refers to a 200 HP kit and to a plug number (QC12PEP) that also refers to a 200 hp. I called the previous owner who verified that he had the kit installed and it was a 200 hp. But it is still a 6o deg. head with pinned ports. My first thought was the new "QC" plug was burning too hot and I needed to put the old (XC12PEPB) plugs back in and see. That was my only other guess. Any help on these or similar issues would be greatly appreciated!!!
