Computer Question
 

My car has been starting then shutting immedatley off. So I got it diagnosed and at first they thought it was my idle speed motor which is part of the throttle body, but my car dosnt start and stop all the time,which it would if the throttle body was the problem. Sometimes it starts the first time so they said its my ECU. Does this sound right?
These are the codes that my car is throwing 16825 p0441 sporadic evaporative emission system incorrect purge flow, 16815 p0431 warm up catalyst bank 2 efficiency below theshold sporadic, 16805 p0421 warm up catalyst bank 1 efficiency below theshold sporadic, 17978 p1570 engine control module disabled. Short circuit to another valve. I just recently replaced my fuel filter, fuel pump(recall),spark plugs(ngk),6 new coils and the battery.
