I feel your pain. My car is same year and engine as yours and does the exact same thing. I too consider myself a good mechanic and this has me stumped. My wife refuses to drive this car because of this. Changed plugs, rotor, distributor cap, fuel filter, cleaned idle control valve, new hoses leading to idle control valve, pulled all relays and cleaned and put dielectric grease on, all to no avail. Please let me know if you find the solution. I love the ride of this car but it does make my blood pressure go up when it cuts off in heavy traffic. I don't want to die of road rage from the driver behind me when it won't start.
