2001 Mitsubishi Eclipse

Engine Performance problem
2001 Mitsubishi Eclipse 6 cyl Front Wheel Drive Automatic 146.00 miles

My Mit Eclipse v6 A/T The car run great, until one day I got oil changed, take test drive everything was ok, but the next morning, hard to start, but when it does I can not rev engine, if I press gas pedal rapidly it will die right away, gentling press gas pedal it will come up maximum. The car can not drive up to 60mph. Wire plug + spark plug +distributor cap + rotor + fuel pressure regulator + 02 sensor all are new. But problem not solve
so it could be EGR vavle?

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
