David,

I tested it with a digital Snap-On ohmmeter. I'll try the analog one.
What puzzles me is that on the digital reading I don't see the
resistance steadily in/decrease, it just jumps around 1400 ohms
plus/minus 200 ohms. All the other resistance tests between the
terminals check out fine.
I don't think I fully understand what and how the Air Auxiliary Valve
works, the one that sits below the passenger side intake manifold.

I am gonna try and do a compression check today. And I have a vague
feeling about that.

Have a nice day
