In what way can my brakes effect idle?

[Milt 92GT]

Well..............

My brother and I figured to go ahead and just eliminate what has been our BIGGEST suspect since this all started...The fuel pump.

We changed it out earlier tonight and when we were done,I started the car.First thing I noticed as I turned the key was that the pump priming was considerably quieter...I never really though it was loud to begin with but,there was a noticable difference.

I started the car and she turned right on....She kinda acted funny at first,like stumbling a bit and then it smoothed out after a couple of minutes. ( I have heard that these cars have to kinda re-learn tier idle after being cut from power for a while)...I waited for the car to get fully warmed up (this is when it usually will start with the idle problem).It didn't dip what so ever.....I kept playing around with the throttle,trying to induce it and it would hold the idle steady...

I took the car out for a drive and stopped softly and hard...held fine...I drove it hard and soft...and still fine....drove it for about 30 minutes,then came back home and let it sit in the driveway idling for about another 20 minutes and it never dipped...Air on and off,and playing around with the brake pedal and nothing seems to induce it...

Hopefully we fixed the problem this time...I'm still uneasy about it...I won't consider it fixed untill there has been no problems for at least a week or two...I'm going to run the self tests tomorrow and see what I get....If this turns out to be "the fix",I am going to kick myself SOO hard for not going with my gut when this all started in the first place!!

Thank you guys for all the help...wish my Stang luck!
