You just need to go through a simple Idle Relearn Process.
The Idle Speed Control motor will cause the accelerator pedal to tap and the car will surge back and forth, actually acting like there is a lack of power during intial startup.
Whenever a battery is changed, went dead or the ECM computer is replaced.
In order to make the engine run normal again, you need to take the car through a relearn process. Otherwise the idle could be very slow or have a 30mph idle.
To enable it to relearn, here's what to do.
1) Disconnect the battery cable for 15 minutes, before hooking it back up.
2) (KOEO) Turn the Key On with Engine Off, just so the electronics are on, but without starting the engine and turn the climate control panel to off.
3) Push the off and warmer buttons on the climate control panel at the same time and hold for up to 5 seconds for the computer to go into diagnostics.
On the fuel panel screen it will display 888 then E52 and then 70.
When it gets to 7.0 shut off the key for 1 minute.
4) Repeat step 3, two more times.
5) Start the engine without pushing on the accelerator pedal and let it run for 18 minutes with the climate control panel off.
6) After 18 minutes put your foot on the brake and shift into drive and wait 1 minute.
7) Then turn on the a/c by pushing the auto button. It needs to be warmer than 60 degrees F so the compressor can engage. Wait 1 more minute.
8) Put the shifter back in park and turn the key off.
9) Wait 1 minute
10) Idle relearn is now complete and the engine should start and run correctly.

Insufficient EGR Flow
What does that mean?
EGR stands for Exhaust Gas Recirculation. It is part of the vehicle emmissions system, and is used to reduce combustion temperature and pressure to control Oxides of Nitrogen. There are generally three parts to the EGR system: the EGR valve, an actuator solenoid, and a differential pressure sensor EGR (DPFE). These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc. The P0401 code means that OBD detected an insufficient amount of EGR.

You may notice drivability problems such as pinging (a.k.a. pre-ignition knock) when the engine is under load or the vehicle is at higher speeds. There may also be other symptoms.
A code P0401 most likely means one or more of the following has happened:
In fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit.
