MY CAR BOGS DOWN ON ACCELERATION FROM A STOP, MORE SO UPHILL.

2007 Saturn Aura • 106,000 miles

This just started a couple days ago. Drove it all day yesterday and nothing happened. Then last night it did it a couple times. This morning drove it and nothing. Then it happened comming out of a red light uphill, but then drove the rest of the afternoon and nothing.

Possibilty 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
