I just bought the car a few weeks a go and the car loose power when while driving but sometime it doesn't do it. I already change the sparks plugs and the fuel filter and ck for any broken or disconnected vacuum lines but evrything seam to be normal. What I should do next?

Lack of acceleration, chugging, hesitating, bogging etc. Could be caused by one of the following below.

Inspect and test all the following listed below and get back with some results

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position 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.
