Are the o2 sensors reverse thread? I have the socket on and it won't budge. I don't want to put a cheater bar on because I don't want to break anything. So can anyone confirm if the threads are normal, or are they reverse?
Thanks,
Val

 

It is right handed threads like most bolts. My 95 Accord was hard to break loose also.

 

Sometimes it's easier to remove when hot.
Use PB Blaster, Kroil, Liquid Wrench or something like that.

 

Thank, got it.
