2024 F150 5.0 Cylinder Deactivation
2024 F150 5.0 Cylinder Deactivation. Is there anyway to test/tell the truck have cylinder deactivation? Your brother likely has issues with shitty lifters that gm refuses to recall, and aren't at all related to cylinder deactivation.
Cylinder deactivation is a very sensible way to save fuel. Has anyone been successful on deactivating cylinder deactivation?
