Advice required in oz re 99 millenia
 

I have aquired a real beaut 1999 millenia or as badged here in oz, a mazda eunos 800m. Have checked out other millie questions and advice given and have got a few clues from you guys, but am now stuck
Car went really well for a while but then started to really sruggle when going uphill. Mega high rpm's but would only go about 40kph, then come good as the gradient reduced, then it started to do the same when taking off from traffic lights on the flat.
And have just worked out that I can buy my own OB11 device, but cant find the port to plug it in, have checked out picture on the web, but cant see anything like that under dash/steering wheel.
Any suggestions muchly appreciated, Rutho

On the 1999 Millenia (US RHD version) the port is to the right hand side of the drivers knee (under the dash) I'm not sure if foreign market releases of this vehicle have an OB2 port. Do other OZ vehicles have OBD2 ports?
