Please HELP!!

Trying to get my 02 SportC to pass inspection and I am having a problem. I am afraid if I can't get this to pass, my wife will make me get rid of it and get a mini van. :-)

According to the tech trying to troubleshoot my problem here is what I know.

Stock 02 is300 Sportcross with 87K miles. W/Trouble code P0125 only. The check engine light comes on after @ 1 mile after reset. All 4 02 sensors replaced less than 5K miles with OEM, and new OEM thermostat. Car runs a little rich but smooth. Heats up quick and maintains temperature fine. Cooling fans come on around the time the thermostat opens.

The tech says the computer log shows o2 #1 bank 1 is dead (no signal at all) yet the ECU does not pick up the code. He also said the log shows a ridiculous amount of fuel mixture in a couple of cylinders which also should be coding; yet no codes posted except the P0125.

He is thinking the computer may be defective. Anyone ever had this same problem, or anyone want to toss some ideas around on what the problem may be?

Any help will be very appreciated. I want to see if there is a fix before I take it to the dealer. (we also checked all the fuzes and all are fine)

Thanks
Scott
