Problem with my Olds Aurora

Engine size = 4.0
dash lights = Check Engine
codes =
P0285 & P0410
work done prior = New (used) compute CPU and new mass air flow
work done to repair = none
tech = KK
question = Car is still stalling when stopped.  Would like to know
where the Crankshaft position sensor is located and if its possible to
repair without much experience.  I read some other threads for the
Cadillacs and people were saying it wasn't that difficult.  Also, is this the
reason it's stalling.  Any help would be appreciated!!  Thanks again,






KK:
Code p0285 does not come up in my list of codes.
P0410 is a problem in the secondary injection system. Possibly a bad A.I.R.
pump and blown fuse,
other commom problems.
A crank sensor can cause staling, but usuually hard starting. They are
located in the center front of the engine block as viewed from under the car.
They are a little tough to get to, even with a swivel socket. They are right
next to the oil filter and oil pressure sender.
