My 2.0 86 Mighty Max is running really rough

Same with my truck it only has the cat in the exhaust pipe but I read the other post im the pcv valve its good, and the gas is only a couple months old but ill add some fresh gas and the timing I can't get it down cause its running rough I have to use the idle screw to keep it running and when I first start the truck up I have to give it gas so it can start or else it will just keep cranking
