RE: need an ISV
This post has intrigued me. Just to recap, my 86 5ktq won't idle. I
can start it ok but have to keep my foot on the gas a bit to keep it
running. If I don't, it dies within about 3-4 seconds, running rougher
and slower until it dies. I unplugged the ISV to see if that would make
any difference and it doesn't, except that when I let off the gas, it
dies right NOW. No 3-4 seconds of rough running, just dead stop. Now I
see that someone else has exactly the opposite effect. Does anyone know
what the effect of unplugging a good ISV would be, and what should the
effect be of unplugging a bad ISV?
