[V6-12v] Low Idle + Oil Light = Fix two problems in one?

[Nathan Widmyer]

I understand that the idle is controlled by the ECM because that was
the failsafe check when checking the ISV, to make sure the ECM was
sending the right idle speed.  I was idling at 700RPM before this
idling problem so unless the ECM code was changed somehow, something
is retarding the idle from 700 to 200 and since I blasted the ISV with
WD-40, I'm looking elsewhere for this problem.

As a potentially related problem which happened before the idling
problem was the oil light.  The light flashes regularly from a cold
start until the car is reasonably warmed up.  I'm thinking that since
the oil gets thinner as it warms up, that something restricting flow
when the oil is thick and cold but dissipates as it thins out.  I
talked to my dad and he said we might change the Oil Pressure Sender
(sensor) which an online place quoted $19.

Anyone think these two are related?
