RE: IML: 66 Imperial IDLE Quality

["Frederick Joslin" <fljoslin@xxxxxxxx>]

In a similar vein, I had a 1990 Isuzu PU with AC. It had a valve which activated with the A/C compressor to increase the idle speed. The valve opened a vacuum line to increase the idle speed. I am not sure how it worked but you sure noticed the difference when the valve did not work.

If you look at the cars from GM in the 80's
they were equipt with a "Idle kicker". When
you turned on the A/C there was a solinoid(sp?)
that would bump the acclerator(at the carb)
just enough to maintain idle speed(700-900
rpm). If you have made sure of all your vacum
line are not leaking that may provide you with
an idea.
