Subject:Do I really need the Idle Stabilizer Valve?
From:Don & Christina Preston
Date:Fri, 21 Sep 2001 23:27:20 -0700

Hello all,

Not long ago, my bus started idling very high, and surging randomly. At idle
(as high as 2800 rpm) I could pinch the hose going from the Idle Stabilizer
Valve to the AFM and idle would return to normal. I even tried replacing the
ISV.

I found that if I disconnected the ISV, the bus would idle perfectly (just a
little low on startup). So, this is the way I've been running it ever since.

So, to my question. This bus originally had A/C and Power Steering. I've
pulled both of these (replaced PS with a manual rack). Since the ISV is used
in conjunction with the A/C and PS, do I really need to have it installed?
Betsy's been running perfectly without it (at least 2000 miles now).

As always, Thanks in advance!
