Something about the Motor Trend article I noticed:
Quote:

With zero valve lift, the cylinders are sealed, and no fuel is injected.

If this were true and the cylinder head is sealed but the piston is still working,
that would cause a huge drag for each of the 3 cylinders for the air compressing-and the following vacume on top of the piston.
I'd venture a guess that at least one valve is open to vent the dead cylinder?
Does anyone here have the HCH service manual?
Perhaps it may shed some light on the subject.
