I don't have a repair manual. I was going to use AutoZone's online free repair manual just to give me the torque spec for my O2 sensor, but apparently my car is so uncommon that they don't have a online repair manual for it.

I called an Acura dealership to get the torque spec and all he told me was "until it's tight, maybe around 50 ft-lbs or so".

Does anyone have that torque spec for my before cat O2 sensor? I really want to get this done so I can move on.

Edit: So I ended up calling another couple of Acura dealerships until one of the guys found the torque spec for me. 33 ft-lbs
