vaccum/missing 86 tercel 4wd carb

[chance_supra]

i need help on trying to remove the vaccum lines i don't need. or atleast fix it. cuz it has to idle around 1000 rpms, and slight miss at idle.. i have changed the dist, rebuilt the carb, changed all the vac lines. most of the vac sensers. sometimes when i stop at a stop sign it dies. other then that drives runs good.gets around 28+ mpg. i no i need vac for the idle up, choke, dist. but want to get rid of the EGR valve.

Heyy - another Show Me person! Welcome to the Club! What was the original location of your car?
Since you have a Federal car and the OE carb - you need the vac stuff. The only thing you can disconnect with confidence is the HAC device and its lines and elect connection - and plug all of them going to the carb and the EBCV. Refer to the vac diagram sticky in the Repair Guides forum. I made some threads on this as well in the Guides and Questions sections in my (elusive) search to eliminate RPM cycling some years ago.
I could be wrong on not being able to disable the EGR valve with the OE carb, though; I did not disable mine until I installed the Weber.

sounds like you have a vac leak somewhere. Use carb cleaner spray with it idling and find where it is leaking. Also check all the vac run devices (like the brake booster and the dist. vac advance), if they are failed they will also act like a vac leak.

Most of the systems have to stay in place if you expect the stock carb to act normal, there are a few you can by-pass. Most will not affect drivablity or economy, unless they are not functioning properly. To get ride of all the vac lines you need to replace the carb with the weber. It is not really that difficult to sort out the vac systems, just follow the FSM proedures to check and test each of the systems.

Good luck.
