I have been trying to remove this O2 sensor from my car the one before the Cataylic converter. I removed it from the exhaust part but I can't seem to pull it off of the electrical connection. Does anyone have any suggestion I don't want to break because it is only plastic? My car is a 1992 Acura Integra LS. Thanks!

 

cut it. alot of O2 sensor's are universal and all it is is a splice and shrink wrap thing.

 

Its probably a little stuck due to grease and dirt getting stuck in there. Just push the clip to unlatch it and just wiggle it.

Maybe take a rag and try to clean it up a bit.

spray the plug with pb blast or wd 40. it should take some time and effort but make sure you are pulling the plug off properly. and when you replace it, lube it up and clean the connectors!
