The vehicle sputters when accelerating, runs somewhat okay with little pressure on the accelerator and stalls in drive when stopped after the vehicle has been running for a while. The engine also has a lot of shake on it, all of which have worsened after changing the fuel pressure regulator, aside from the engine shake. The car computer also reads the exhaust gas recirculation sensor low, but doesn't have one on that model. The fuel pressure regulator looks to be operating normally, no leaks, good gaskets. Fuel filter is new as well. What could be the cause?

Lack of acceleration, chugging, hesitating********, 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.
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.
