I have a 1984 Carrera 3.2. Plug #3 continually fouls. I heard that it could be a 'leaky injector' that keeps wetting the plug and therefore preventing it from firing. Are the injectors replaceable?

Yes, a professional mechanic can do it in about an hour and a half. Did you pull out the spark plug to verify the plug is gas fouled? You can have a bad valve guide seal and the plug may be oil fouled.
