O2 Sensor

[deepsouth]

Hey guys,
So slowly fixing up bits and pieces on the old beast that the recent trip to the mechanics found.
Still one thing that is undiagnosed is the dodgy idle and running rich, i'm organising the ICS from a magna to rule out the ICS and then I have a spare ecu to try as well.
In the elimination i'd like to rule out the O2 sensor but for the hell of me I cannot find any part numbers for the beast.
I have this one from NGK which I pulled from the EVO3 tech thread... OZA624-E2
Not sure if this one will work, any help would be greatly appreciated.
Thanks

As I don't know your year and model take your pick. http://mitsubishi.epc-data.com/rvr/n23wg/snxm/engine-electrical/electrical-control/18107,18108,18114,18119,18124,18131/

Thanks p055um5, its a january 97 Hyper sport gear R, apparently, that was the build plate date at least.
I got MD176245 as the reference part number, that is one hell of an expensive sensor...
The NGK one was only $45 shipped...
Better see what the equivalent might be if there is one...
