What is the most likely cause of high hydrocarbon readings?

Lean Fuel Mixture - Any condition which will cause unmetered air to enter the intake manifold, and ultimately the combustion chambers, will cause high hydrocarbons (HC).

This condition is called a lean miss-fire.

Such faults as vacuum leaks and gasket leaks will cause lean fuel/air mixtures.
