Check the exhaust system could be a clogged catalytic converter if okay check the fuel pressure with a gauge and comeback with the readings we start here.

Exhaust is clear and I repaired main fuel pump (hasn't worked since I bought the car lol so have two pumps now, no difference in problem) my friend thinks it could be the mass air flow sensor (filament intact and clean) and wants to know if there is a way to test.

Inspect and test all the following below
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Manifold absolute pressure sensor.
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.
