Hi Ron

Haven't done much with PCMS.. Generally you can replace the
solenoids with 100 ohm resistors. Certain solenoids open circuited
will cause a fault condition. With OBD 11 who knows.

There are various states of limp home in the PCM.. I seem to 
recall the airpump getting your into one of these since
it is electric and controlled by the ecm.. 
anyways try putting 100 ohm ala skip shift resistors whereever
a solenoid is supposed to be.

There are more complicated routines to find malf egr ect but
they won't report directly
