Hi folks,

I did the simple "hose pinch test" for the AAR in my '84 1.9, stone cold,
and there was no effect on RPM. (Bentley 24.28) I assume this means the AAR
is stuck open, as the van starts instantly and runs and idles well when cold.

However, once warmed up, the idle fluctuates, and once in a while the engine
runs extremely lean on acceleration.

What effect could the AAR sticking open have on running conditions when warm?

Are AAR's fixable?

I ask this because a quick search of the vendors reveals almost none in
stock, and the one I did find (at a place called Rapid Parts--?) costs
almost $80.

This raises another, more general question: what do we do when this kind of
part is NLA everywhere?

Thanks,

Geza
