Yes, and I checked all the fuses last spring when it was doing
this. If memory serves, these components are on different circuits,
but fail simultaneously. SO maybe it is a ground problem under the dash?
Last night was raining and near freezing. I want to try working on
it inside, in the dry, with light, and preferably when it is not freezing.
I found a couple of places on the MAS screen where the plastic was
broken, but hanging at an angle, which could cause turbulence. Also,
the oring to seal the MAS to the air filter box had been out of
place, which might also cause some turbulence. I am assuming that
turbulent flow might cause a false reading. We will try running it
today. When i worked on the car this summer, I did not remove the
air cleaner top from the MAS body. If I had, I would have found the
oring out of place.
Is there any way to test the MAS out of the car with simple
equipment? Ohmmeter or voltmeter...

I will try to check out the MAS and o2 sensor components tonight or
tomorrow. Anyone have advise about how to check them other than
buy a new one and replace it like the dealers do?
Now there are other symptoms:
Error code 10 MAS voltage too high/too low (TENDS TO INDICATE THE
mas IS THE CULPRIT)
Turn signals/emergency flashers/rear defrost don't work. All have
intermittently worked or not worked. Not sure if this is unrelated
or related to the idle problem
TIA
