What causes spark plugs to soot up?
Soot, or dry fouling of the plugs is a result of unburned fuel. The causes are (in order of likelihood) 1. Not enough air. 2. Weak Spark. Failed spark plug(s). 3. Too much petrol. 4. Ignition timing incorrect. The main thing to establish is the soot on all plugs or just one or a number. If all, then 1,2,3 & 4. If just one or two, or a bank if multi carbed, then focus on that bank.

It could be a bad oxygen sensor or the wiring to the oxygen sensor. This is not the only possibility. Could be a computer issue. not sure what else. If the spark plugs and O2 sensor are all black, then the injector may have failed.
How do you know when you have weak spark plugs?
If the spark plug end (combustion chamber end) is coated with dry, black soot, it indicates weak spark or incomplete combustion. Note that this doesn't necessarily mean that the plug is bad; weak spark more often indicates a faulty coil or plug wire or, sometimes, an overfuelled cylinder.

95 integra gsr wont start keeps cranking and sputters like its about to start but doesnt. Its throwing out white smoke from throttle bodyleaving behind black soot. New spark plugs were black and damp?
Black and damp spark plugs are a sign that there is either too much fuel in the combustion chamber or not enough of a spark to ignite the fuel. The white "smoke" you see coming out of the throttle body are fumes from the fuel. You might want to check the condition of the inside of the distributor cap or the rotor tip for corrosion. Also inspect for cracks on the distributor cap and the condition of the spark plug wires (both ends - but especially where they plug into the distributor cap).
