Engine Performance problem
2002 Buick Century 6 cyl

my car is having trouble acceleration
As I accelerate, it slightly shakes and feels like it has trouble getting to 30 mph. After 30mph, it will rev but not accelerate at all which causes my engine heat to rise past normal. What could this be?

Lack of acceleration, chugging, hesitating, jerking, bogging, misfiring etc. 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.
False air leakage.
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
