    Intake and exhaust valves close ( valves deactivated ) and fuel in those 4 are turned off.

    Air in cylinders simply compresses and expands. Still has some heat loss and friction but still saves fuel.

    On a side note, I had a GM ls4 the did the same thing, After a few years of it, It caused lots of problems, I would have it tuned out...Just my thought

    I am on 3 years in my Charger with this and haven't had any problems at all. I would be interested what some of the issues were also.

    Spark plugs going bad,,, and blue smoke coming from exhaust, it's like it's flooding the cylinder,, at least this was a very very common problem with the ls4,,

    I had a 2007 Impala with a V6, never had any problems with
    the engine, it had the cylinder deactivation deal.

    I'm talking about the ls4 , not the v6,3900 or ,3500. I'm talking about the v-8.. 5.3 liter
