Spray starter flues in the engine and try to start it. If it starts with your foot on the gas and it revs but wont idle start it again. rev till car is warm and if you let go of gass and it idles your idle valve is good. If not bad. your symptom of driving stopping then taking off and it dies sounds like you have a sensor problem. Mine was my temperature sensor. ( the one that controls the computer) But first put new gas in it change fuel and do what everyone else says. I wanted to tell you my story wcause my symptoms were simular.
