“It sounded to me like the engine was having more than one problem.”
Inactivating some cylinders sounds like a good idea. Hasn’t Cadillac has been doing it for several years?
But why not do that on the cheap cars, bought by people that really care about miles per gallon?
My guess is that they just keep the valves closed on the inactive cylinders, but I don’t know how they do that.
