You can get away with murder with the 80sx until it comes to tickover, then things have got to be just right. Check your plugs and plug leads. If you're in doubt change them. It only takes one plug lead tracking to earth. Make sure your air filters clean. If in doubt, change it.
Then reset your ECU to let it relearn the new changes. (Disconnect battery for at least 8 hours)

Check how she idles then.

You can check out fault codes here http://www.systemsc.com/codes.htm
It's saying MAP sensor but fault codes only put you in the right area. Other things could be causing the problem like an air leak, poor electrical contact on the sensor, it could even be a dirty idle air valve

I'd check the MAP sensor electical connector and then stick some carb cleaner down the idle valve intake and see what happens
