One more question, Is any of these sensors we have talked about difficult to replace, I retired from GM and have been a shade tree mechanic all my life including aircraft in the army. I just replaced two oxygen sensors #1 bank one and sensor #1 bank two as I had codes as bad these codes was corrected, but still have the code P0101 showing.

Thanks for all your help.
