I want to replace my front o2 sensor but I have this problem. I'm a bit embarrassed to ask but I can't disconnect the plug .There is a lever or tab on the top. I tried pressing down or lifting up but can't get the plug to come off. I don't want to force it and break the tab off because it looks kind of delicate.I'm sure there is a certain way they come apart but I can't see it. any help would be appreciated.
