86 cj7 vacuum question
Well, I am the happy owner of a new 1986 cj7, with the 258 motor. The
previous owner completly disconnected the computer -- the wires running
into the firewall are cut off flush. It looks to have a stock carter
carb. Could someone here please describe to me how the vacuum lines
should be run -- the minimum needed. Also, what needs to be plugged up.
The previous owner has modified the vacuum system somewhat, and I want
to check what he has done. The jeep runs good, but wants to stall in
cold wet weather. Thanks for the help.

Re: 86 cj7 vacuum question
Hoo boy...
Ok, I have the minimal vacuum routing. I just have the PCV, EGR, air
filter flaps and charcoal canister (gas tank and float vent) hooked up
with no computer.
Here is a decent link on the computer modification and the vacuum
routing on the 258.

Have a look there and if you have questions, just ask.
Running bad when wet implies a dirty distributor cap and rotor to me.

Re: 86 cj7 vacuum question
That guy save you some big headaches. It's called the Nutter
bypass: http://home.sprynet.com/~dale02/ignmods.htm You probably should
go around hiding the obvious disconnects to keep the SMOG ***** happy.
Maybe turn the choke spring up a notch, or cold idle cam.

Thanks. So how do I turn up the choke. Also, the EGR vacuum hose is
disconnected and the nipple on the EGR is plugged. What is the effect of
this?
