Question about 1990 Nissan 240SX
I can't say with certainty but I know some vehicles whenever a sensor is unplugged will default to a pre-determined setting. When the MAF is unplugged it might be going to that said value. Does it run well through the entire rpm range? or just at idle? I would think that your MAF might be dirty and when it is plugged in it is not reading the correct air flow. This is very prominent on vehicles with a/m oil bath air filters installed. I would try cleaning it first and if that doesn't seem to help try replacing with a known good unit. I would imagine if its a KA then any local wrecking yards should have a couple kicking around.
