Fouled Spark plug?

[asecretfile]

91 coupe....what are the most obvious signs of a fouled plug or bad plug wire?

Basically what its doing is when I get on it a little its like it spits, then pulls spits then pulls...it never stalls out just feels like losing a cylinder, comes back a second etc etc...duration maybe a day and a half

If its possibly plugs plug wires, is there a way I can isolate or is just best to go ahead and replace them all while Im at it?

Thanks

Pull the plugs and see what they tell you. A fouled plug will look bad. Tan is the key to good health. You may have bad wires, cap, roter or TFI. Maybe a bad hall effect in side the dizzy but thats on the very end of the scale.
