Rough idle 700 1990

Try turning on the ingition for 5 seconds before starting the car. If that makes it idle better then the problem could be a weak fuel pump or a leaking fuel pressure "hold valve" on the pump that's suppose to maintain pressure in the system when the pump is shut off. Could be that leaking injector too or maybe a bad fuel pressure regulator. Try some injector cleaner in the next tank of gas.
