I have to replace the pre-cat oxygen sensor, and cannot get the connector to separate. I have tried all that I can, and even broke off the plastic tab in the pic. Anyone have any ideas of how to do this without breaking anything else? Can the connector be removed easily from the metal bracket to provide better access?

Thanks in advance.

 

Check under "DIY oxygen sensor replacement" on this site where they explain the use of picks to get the connections lose.

 

Thank you, I'll try that. Well, after I've finished the "honey-do" list. I've been working away for the last 2 months, and have a load of things to do around the home. Haven't even driven the Coop yet!!!!!
