ICV and TPS... lack of fuel?

I was wondering about these two sensors and have had a search and can't find much information relating to my latest problems.

 

The engine drives fine when cold, as soon as everything warms up and the fuel is reduced from cold start it begins to misfire.

 

Could one of these sensors be faulty causing a lack of fuel when the engine is running warm, having white plugs I am pushed towards the idea of a lack of fuel. I am changing ignition components to eliminate that but am trying to understand other components as I had one of these sensors flash when I had a water leak.

 

Thanks :)
