Just bought my first GN, and I am getting 13 and 44 error code messages. I beleive car is running rich (and may have been for some time). I have the symptoms I have seen described when you have a bad O2 sensor (poor fuel economy, loss of power, stumbling during acceleration) and plan on testing it as described in the technical pages.
One thing I couldn't find is how to get the darn thing out! Is there a trick? I don't want to break anything, but it doesn't want to seem to budge. I have cleaned it up on the outside and sprayed WD-40 on it to loosen it up, but it doesn't seem to help. Somebody please advice on the best way to remove before I end up breaking something.
Thanks, Chris
USE A 7/8" OPEN END WRENCH,A LARGE ONE. IF YOU CAN'T BREAK IT BY HAND TAP IT LIGHTLY WITH A HAMMER

Yeah i just learned that today, after spending half an hour tryin to figure out and find what size wrench i needed (my dad's tool box is a mess). then i couldn't loosen it up, so i tapped it with a rubber mallot and it got loose no problem.
