More Questions -- 88 5KSQ

[urq]

That resistor is only used to determine fuel consumption ... the ECU does
not need this input at all.

If you needed to replace the part I'd say to swap the entire plate ... they
have to be pretty available in the used parts market.  The plates themselves
are quite swappable ... I took a plate from a MC-2 equipped 200Q and mounted
it on the airbox for my urq.  The only thing to beware of is the shape of
the funnel that the airflow plate moves in.  I have no specific data on how
compatible they are, but I would assume that a non-turbo is incompatible
with a turbo.  You may be able to use the part from a 4kQ or 90Q ...

The saga continues. Today my mechanic told me that the position sensor
mounted on the side of the MAF meter is bad; he says that it should have
linear resistance but mine simply goes open. He says that it does not appear
to be a replaceable part. He also said in all of his years of working on CIS
systems he had never encountered anything to make him check this component
and does not really know how critical it is to the operation of the vehicle.
I hope that someone has information on how critical this posiotion sensor
is. I would also appreciate any infomation on the years/models?that have a
MAF that is interchangeable with mine. Once again the car is a 88 5KSQ; this
is a normally aspirated car. As always your thoughts suggestions are greatly
appreciated.
