Question

Answer 1

P0191 Fuel rail pressure sensor "A" circuit range performance

P2008 Intake manifold control runner (IMRC) circuit open bank 1

The fuel rail pressure sensor that when you get this code, There is no use in taking fuel pressure test, You just replace the rail pressure sensor, As for the IMRC (P2008) this will not cause you to stall out or to hold the pedal to keep it running, You may have a problem with the IAC (Idle air control valve) ,The IAC cannot be cleaned out , in order to restore it,and a faulty IAC does not have to produce a code at all.
