Possibilities:
- Ignition: check plugs, cap rotor etc
- Fuel pressure, Failed fuel pump or regulator, Check pressure at port.
- Control system readings incorrect. Need to get car onto a scanner and see what readings are out of calibration. Throttle position sensor, MAP sensor (Manifold Absolute Pressure), O2 Sensor could cause this if it is disconnected or way out of range
- Plugged exhaust system, Muffler or Catalyst or has some one stuffed something in the tail pipes?
- Plugged air cleaner.
- Internal engine problem like a bad camshaft

Will the transmission from an 84 fiero fit a 87 fiero?
Physically, yes. GM's drivetrain are highly swapable. But there can be lots of differences. I'm assuming you are pulling "x" tranny out of an 84 to put in a 87 that had "x" tranny. Not pulling an "x" tranny out of an 84 to put in an 87 that had a "y" tranny. The devil's in the details. Flywheels might not be the same. Most auto part places have the info and will glad to help.
