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. -- Sleestak Registered GNU/Linux user number 281031 http://counter.li.org/ Say NO! To TCPA! http://www.againsttcpa.com |

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. http://home.sprynet.com/~dale02/ignmods.htm http://home.sprynet.com/~dale02/vactails.htm Have a look there and if you have questions, just ask. Running bad when wet implies a dirty distributor cap and rotor to me.

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 nazis happy. Maybe turn the choke spring up a notch, or cold idle cam.

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? -- Say NO!
