305 tbi won't hold idel. i did plugs wires cap rotor fuel pump new vaccum lines, injectors are clean as well. there is no timing tap on my motor so i tryed to turn the cap by hand (old school timing) the car runs and drives great but after runing more than 5min when coming to a complete stop it will idle low and die seems just like you just turned the key off. i can't tell excat timing do to no tab. it's a tbi with a round air cleaning like you would run on a carb.
