Was the humidity really high? It sounds like you need a tune-up replacing the cap, rotor, ignition wires, and spark plugs. Under high humidity conditions the secondary ignition system breaks down and the spark doesn't get to the worn spark plugs. Once you get the motor a little warm it is fine. To complete the tune-up you should also replace the air filter, the O2 sensor, clean the fuel injectors, and adjust the valves. You should make sure all the engine systems are functioning, check the timing, and no vacuum leaks. Don't touch the mixture screw. If it was properly set in the first place it should not need to be touched.
