WHY DOES MY CAR HESITATE ON ACCELERATION.

1996 Ford Aspire • 26,000 miles

The car runs fine until the fuel tank is between half and quarter tank.
Is there a dip hose that might have a break in it (inside the fuel tank)
that would cause this. Like a drinking straw with a hole in the middle.

Possibilities here could be caused by one of the following below

Oxygen sensor.

Catalytic converter.

Fuel injectors dirty/sticking.

Mass airflow sensor/Airflow meter.

Throttle position sensor.

Crankshaft position sensor

Knock sensor

Manifold absolute pressure sensor.

EGR Valve

Fuel pressure regulator leaking or defective fuel pump.

Fuel contamination.

Foul/defective spark plugs.

Open spark plug wires.

Ignition coil/Coil packs defective.

Incorrect ignition timing.

Cap and rotor.

Note: If it doesn't apply disregard it and keep testing.
