Help solving codes
Could somebody tell me the meaning P1646 & P1647 if it's the oxygen sensor , can I use the same part for both sides? or is different part replacement for driver side and passenger side. Jag XJ8 2004. Thanks a lot for your comments!!

Historical Codes
Also it shows long-term fuel trim Bank1 - 1.56 percent, Bank 2 - - (minus) 7.81 percent and all the signs that an old-fashioned and outmoded car restorer like me can easily read are that my car is running too rich, a smell of petrol at the exhaust and occasionally smoking and misfiring through the exhaust.
Joesoap, as you can tell, I am very new to this code reading business!

Closed loop refers to the car's engine control (using the O2s) not to the O2s themselves. They could be out of spec somewhat and it'd still use them (what choice does it really have?).
If the MIL is off check it self-tests when you turn the car on and if it does you've no current codes.
