Ok, my car has had a problem for the past month or so. It will startup and drive for a short distance then eather die while driving or not start up for a while after shutdown. When it dies while driving there is no hesitation or stumbling just straight flatline on the tach and the buzzer. When it wont startup after dying or shutting off it will crank and crank but won't start for a period of between 30 min to 2 hrs. I have recinetly put in new plugs and installed a new ignition control module but it has not changed at all. The car when running also has a low idle and sometimes won't idle and stalls. The car is a 1990 35th auto. with around 80k on the clock and 1 week old headgaskets.
