Ok, I have 3 of the 4 O2 sensors replaced (yes I got Bank 1 upstream and bank 2 downstream replaced fine after heating the bung hole) Now I need to replace the Bank2 downstream sensor. I kind of followed up the wire to the passengers side of the transmission. Is there an easy way to get the connector off or do I have to physically rip the connector assembly off to remove the old O2 sensor.

Thanks, Jon

 

They can be a pain. There should be some slack.
