Ok guys so i've been chasing idle and lean demons since my MAP sensor went down couple weeks ago. I've since replaced the MAP and IAC and now my problem is this:
When in gear, idling and at a stop, vacuum goes anywhere between 12 and 17. Out of gear it...

Here is a quick drive.
The reason I ask is the Velosyty chip looks at the IAC when doing idle fuel to try reset the IAC.
What do your IAC numbers look like at idle? With the truck warmed up, in park, it should be somewhere around 10-30.

I was playing around with my timing advance today after reading a couple of articles on setting the timing advance by a vacuum reading.
I originally had it set at 12* and ran fine, but wondering if it was really where it needed to be.

I've had a couple of problems since driving my XJ again after a year of sitting. I've had a stiff brake pedal (all the time), occasional ABS light that stays on for about a minute and now I've got a funky idle. I'm thinking it's a vacuum leak somewhere...

For a first step, disconnect the brake vacuum line from the manifold and plug or cap the connector at the manifold.
Maybe a cracked blow it apart.
Check hoses, check valve, and diaphragm itself.
Part of the brake system uses vacuum.

Engine was fluctuating worse before I found and replaced cracked vacuum hoses, but did not find any more bad ones, sprayed starting fluid around with engine running to see if any more leaks. None found.
Then I hooked up vacuum gauge and it measures like...

Is there a specific place to plug the vacuum line into for a vacuum referenced fuel regulator? I have mine plugged into the back of the manifold instead of at the base of the throttle body. Is there a difference? I go to car shows and people tell me I...

What do you mean by tuning? Just idle? Then you would have low pressure pressure.
Have a vacuum reference.

If these tear, it can cause that issue.
I would look here.
(Grease one end of it.)
Stick that end up to your ear,
and use the hose like an antenna to find the leak sound .
Grab a yank of heater hose.

I had the same line pop off before, but I was reading about 18:1 at idle so I was running obviously lean.
I was told that if my AFR is above 15.3 at idle take the TMIC off.
I've check for leaks found none.

If you use a aftermarket air cleaner that does not require that vacuum hose then just plug it.
Jeff,
My guess is that is for the hose that goes to the ThermAc (vacuum-acutated flap in the air cleaner has been removed.

Your best best:
kill the vacuum back up the table with pg_dump -t option drop the table restore the table If you are using 8.x, look at the autovacuum options.
This exact same scenario.
