Subject:All Is Not Well in Air Conditioning Land
From:John Rodgers

After all my excitement about having air conditioning - a new problem
has reared it's ugly head. Out of control RPM.

After I got my AC system working - I noted the engine idled way to fast,
even with the AC turned off. Work associated with the AC effort was
getting the vacuum lines connected correctly - which they were not. Now,
with everything as it should be - apparently - the engine idles to fast,
as I said, even with the AC off. I went through the idle adjustment
procedure per Bentley, and with O2 sensor and ISV disconnected, and
engine warm, it idled perfect - 850 +- rpm. When I reconnected - the
engine died. Repeated the procedure, it will not idle when O2 and ISV
are reconnected,  I could only get the rpm by adjusting while the ISV is
connected - and it is approximately correct but still is a bit to fast.
I can leave the ISV disconnected and just run it - which i have done for
years, but now I have the AC working, I need that to work in conjuncton
with the AC to keep the engine from stalling and it's not happening.
Anyone have any ideas?

Thanks,

John
