I'm looking for people who have actually changed this part on their car.  I tried the other day, but couldn't get the connector to seperate.  I couldn't even get my thumb and forefinger around the damn CPA on the connector.  I gave up after an hour or so.  Any help?  I was going through the wheel well on the LH side of the car to get to it.  Any other ideas from people who have actually done this?

Do they do inspections in your state? Might just be easier (and cheaper) to put an 02 simulator on there and take back the new one. They are like 80-100 aren't they?
 
 
try a small pocket screw driver to pry it apart or a pick tool.
