Trying to replace couple of O2 sensors that are reporting errors. It is so tight and hard to remove. Don't want to end up breaking anything. And don't want to use any penetrating oil that might cause headaches later.

Also need advice on using the existing connector and attaching the new sensor wires as they don't have the connector. Should I use the something specific like posi waterproof connectors?

Advice appreciated. Thanks.
