Angry 90 YJ jolts, sputters, rpms bounce, and dies

I have a 1990 YJ 4cyl. I will be driving down the street and randomly the rpms will drop/bounce and it jolts a few times, its like it wants to go and it also wants to stall, and will go back to normal. It was only happening a few times now i debate driving it some days. When it dies it takes a few times until it goes again. Sometimes it dies at stoplights sometimes it does not and also turning onto a street the rpms will drop and it dies. Things I have replaced-- spark plugs, distributer cap along with rotor, fuel filter, and I have also put octane boosters to burm any water in the tank. PLEASE help, anything would be appreciated.
