Default where is the knock sensor located on a '95 SE?

My car is running poorly lately since the motor swap. For one, it'* running very rich and galloping while idling in gear. Also not wanting to start. The CEL is on, so I had it scanned last night. One code was for the knock sensor voltage. Another for the EGR, another for the 02 sensor. I found the EGR cleaning procedure and will take care of that. I'll also replace the O2 sensor. Where can I find the knock sensor?

Is this a 95 SE with the 3800 Series II engine?

If it is it has a knock sensor on both banks

yes.....it'* a 3800 series II

would the scan specify which bank was giving the bad reading or would I need to just check/replace both?

You would most likely need to check both... They are in line... Not sure how they worked it out, but its 2 knock sensors on a single wire..
