I have a 1991 Mazda b2600i 4x4 and only when it gets cold and damp and starts to idle rough and spits gasoline but when I leave it warm up for a while it makes a clicking noise then runs perfect...what could be wrong with it?

Could be coolant being burn in the combustion chamber and when it heats up it seals the leak-

Recommend you have it block and pressure tested.
