Need vaccum line diagram for 95 mustang 3.8 liter with aod trans please help

SOURCE: eng. rpm not dropping when clutching & at idle, rpms go up & down

Here are a couple things to try. The idle surge is a common problem. Ford makes an adjustable plate like the one below. It allows come control over your idle. I made one and it eliminated most of the surging. I think the Ford part is about $30. Can't seem to find the ford part number though. Search online.

Try www.fordfuelinjection.com or other ford sites. Lots of great information.
My 89 seems to roar loud when cold when coming back down to idle and I am sure its the fan clutch. I have also heard the water temp sensor can cause idle problems because the EEC does not know what state the engine is in. (hot/cold, etc)
Hope this helps. I do recommend the adjustable plate though.

Are there any performance mods done to the car?

They don't make diagrams for brake lines. The lines are sold in bulk. You need to measure and duplicate the bends in the orignal lines and cut/flare the lines yourself. You will need a tubing cutter, flare tool and tubing bender.

Sounds like one of the seat valves is coming out of place. That same scenario happend to me with the two 1995 Ford Escorts I have.

SOURCE: I have a 95 mustang that starts runs for awhile

what about the idle air control valve,for a 95 they should be adjustable. (some parts have a tiny access hole).then there is the EGR when you running and coming to a stop there are time the pintle doent close on time, you can try do disconnect the line to the EGR just to test it out to see if the fault is there but do not leave disconnected not only is it emission violation but it can make combustion so hot internally as to put a hole in the piston but just to test on coming to a stop sign to see if the problem is EGR related.
