if you want to look for the Oxygen sensor, it is under the car, in front of the Catalytic Converter. Need a special tool to take it off. But, I'm telling you, dying at a traffic light is nearly always: 1) ISV, or 2) Vacuum leak.

Why it dies when you press the brake? Brakes use vacuum, which is already low from the leak.

do your RPM's bounce up and down at idle?

Yes, I went to school with Ric. He was into RC pretty heavily.

Is he still around?

If so ask him if he remembers;

Wilber
Eddie Murphy
Marvin
C. Parke Fry
Killer
The worm

Tell him you talked to "dad" from RIT.

MY AUDI 80 91 STANDARD DIES OR THE RPM BACK TO ZERO EVERY TIME I PRESS THE CLUTCH AND LET GO EVERY TRAFFIC LIGHT OR ON TURN.

I CLEANED THE ISV IT LOOKS OK CAUSE I HEARD
THE SOUND LIKE T-CLICK, T-KLICK WHILE THE ENGINE IS RUNNING, MY PROBLEM NOW HOW TO CHECK THE LEAK OF THE VACCUM OR WHICH ONE CAUSE THERES A LOT OF AIR HOSE AND O2. I HOPE THAT ONE OF THIS IS THE PROBLEM.

Some things are not worth the hassle and frustration. Vacuum leaks can be tricky to find on your own. O2 sensors are quite pricey and you would hate to replace a perfectly good one.

A bad O2 usually will cause poor running, generally not what you describe. You have a major fault.

I just clean it and reinstall it and it works!!

I posted below but I guess you didn't see it.

Scroll down and read my post about Ric.

I know this is an old post but a bad O2 sensor can do EXACTLY what you described.
