What is code 85 and a CANP?

New member and this is my first post, so I hope I did it right. I have a 92 Stang with cold idle problems and hot idle problems. I know I need to put in an ACT sensor as I dont have one, and there is no vacumme line to the PCV valve (it is capped), so I will fix that but I am getting a code 85 for something called a CANP, what is that?

Just bought the car and was told it is a 306 with a lunati voodoo cam (dont know specs), 24lb injectors, typhoon intake, 65mm t-body and spacer, under drive pully, mac headers, mac h-pipe, mac exaust, pro-m mass air for 24lb injectors, and 3.55 (which I doubt because with the black 20 tooth gear at 100 on the speedo I am actually doing 118), new world class t-5 (that does not stay in reverse) etc.etc.etc.

This is my 6th Mustang and I will never drive anything else.

I assume the hole in the Typhoon intake is on the upper plenum facing foreward on the neck after the egr spacer Right now there is just a plastic screw in there. I know in the stock one it sits in the lower between runners one and two, but there is no provision in the Typhoon there, so I think the other hole is it. I just have to go to NAPA and get one to see. And yes my charcole filter is gone. I see the vent line from the tank run until just under the passenger seat. I would like to do something about that because I can really smell the vapor when I run it in the carport.
