i am getting 12 mpg combined on my 86 n/a 300zx! it runs rough and is slow as well. what can i check? MAF? TPS?

Do a full tune up, check all sensors for corrosion. If the car is out of tune there could be a number of things that contribute to bad gas mileage. The main thing that usually causes bad mpg is the 02 sensor but again if the rest of the car is out of tune then you could get lower mpg too.
