My 99 chevy tahoe misfires after a rain or when its damp. I've replaced the distributor, ignition wires, rotor button, and sprayed everything with silicone. After the car warms up, the misfiring stops. What is causing this problem?

Could be dirty injectors. I recommend having them professionally pressure cleaned. Nothing added to the tank will help.
