Motor surges at highway speeds
2000 OLDSMOBILE ALERO
Why does my motor surge when I'm at highway speed usually when I'm going up a incline
have the same problem?

Could be caused by one of the following below:
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Manifold absolute pressure sensor.
Fuel pressure regulator leaking or defective fuel pump.
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.
