Hey everyone
So I got my y-pipe off of my 98 Jimmy SLE ( because it was rusted around the o2 sensor on passenger side and making an awful noise) that was a task on its own original y pipe, truck has 250,000km on it. Anyways I got one o2 sensor out from the bung on the drivers side, the other one came off with the bung and I have tried and tried and tried to get it off with heat everything but no luck. Im wondering what the proper o2 sensor is to buy for passenger side which is s1b2? If im correct may be wrong, Looking on amazon I found, But it doesnt look the same as the other one that came off, the one that came off looks more like the second link, but its not the proper wire connection, any help is appreaciated, thanks.

 

anyone?
