New owner of 2001 aurora
 

Hey all, Proud new parent of a 2001 aurora, sweetest ride I've ever owned. Usually do all my own wrenching but I gotta admit the amount of electronic controls on this car is a little intimidating for a hobby mechanic.
Is there a list of common facts or problems the collective here could point me towards, I have a lot to learn, like why does the oil pressure say 130lbs all the time? that cannot be right, why do the headlights intermittantly briefly dim like something pulling a big load just started? Don't want to burn up a bunch of bandwidth asking questions that may have been answered a dozen times already.
