I'm not for sure because i dont have a jato. but if u take ur air filter off. and watch the carb while adjust the idle screw u should see it move a little at a time. so u want it set were when u apply ur brakes ur car still idles w/o dieing

still no good I'm bringing it in for a tune up boys i am stumped

Your idle stop screw is too far in. When you hit the brakes it closes your carb up all the way so no air...it dies. On the 3.3 it is on the RHS of the carb behind the air filter. The best way to adjust it is to turn on the radio and open the carb fully the turn the screw in 1/8 turn or so then try it again

Just to make sure you CAN'T turn off the engine by hitting the brakes, make your idle adjustment with the trim knob turned all the way down, and the brake applied. Then set your opening.
Make your final adjustment with the engine running. I only use the idle trim knob during warm up.
