I JUST GOT A 91 240 SX WITH A KA24DE... YES IT IS AUTOMATIC.. THE DUDE SAID THERE WAS A LOSE OF POWER BECAUSE THE MAF SENSOR NEEDED TO BE REPLACED.. BUT I BROUGHT ONE AND IT DOES THE SAME THING.. THE CAR ISNT THROWING ANY ERROR CODE.. CAN ANYONE GIVE ME ANY SUGGESTIONS ON WHAT IT COLD BE.. THANKS A LOT

STOP YELLING......

Is it running lean or rich? Could be an injector issue, could be as simple as a fuel filter. Being you just bought it I would do....
Plugs, wires, cap, rotor
PCV valve
Fuel Filter
And a seafoam job.

To check for a dead injector.... unplug each injector one at a time with the car running, if the idle gets worse, move on. No change the injector is not good. Now a stuck injector... pull each plug and check for unburnt fuel or it will be black then the others.
