Hey there, does anyone have any suggestions for removing an o2 sensor? The car is a 97 Integra LS, and I'm trying to remove the primary sensor from the factory downpipe. It's a 10 year-old car and I do live in Michigan, so I'm guessing it's just rusted and baked in place pretty good. I have one of the o2 sensor removal sockets and I've been dousing the threads with penetrator but it doesn't seem to be helping. Any other suggestions? Also (and sorry for the retarded newbish question here), will it hurt my car to be running around with the CEL light on for a little while until I get the sensor situation fixed? I recently installed a header and that's why I'm needing to transfer the sensor over. Right now the sensor is just unplugged and I capped the threaded hole in the header.
