Default Another, yes another Check Engine Light

Here are the particulars, I have an 2004 XJ8 Vanden Plas with 58K on her. Last week I noticed a little bit of rough idling at a stop but paid no mind because I had no check engine light at the time and it was pretty cold out, so I continued on my way. Approximately three (3) days ago I was driving along and I looked down at the instrument cluster and saw the omnious orange engine icon there. So I unfortunately had to continue on my way because I was already late for work. I go to Auto Zone to get them to read the codes for me, she threw a P1111, and a P0443 (pending) at me. After much research on the forum I have found that noone else has had these codes at the same time, so I am limited to piece together info for myself. Only problem is that when others have these codes thay are accompanied by codes that I do not have, so there diagnosis does not fit my problem.
Can ANYONE shed some light on this particular issue that I am having?

The P1111 just means that components have passed their tests over an extended period. If you erase trouble codes it will change to P1000. The other code has to do with the canister purge solinoid. It may be a temp problem. Always check wiring first. Unplug the valve and use and ohmeter to see if the solinoid is okay. Look at the contacts at that time.

Thanks for your answer. Where is this wiring located on my 04 XJ8? I have and ohmmeter, what am I looking for when I test? am I looking for voltage, resistance, or continuity? also what will the answer tell me about the solenoid? ex. (Continuity means it's actuated, is it supposed to be?) Thanks again for your help!

P1111 is good, and will not put on the light.
A pending code also should not.
If your light was on, looks like there is another code somewhere.
