Are there any AFM problems with the GM 5.3L V8?
Now, to be fair: Not every GM 5.3L V8 has problems with AFM. Many consumers report a trouble-free ownership experience. Still, AFM problems exist. The AFM excessive oil consumption problem usually crops up on vehicles that go on long highway drives. These kinds of trips don’t put much stress on the engine, so the AFM system deactivates pistons.

How does VVT work on a 5.3L V8 engine?
On the 4.8L, 5.3L, 6.0L and 6.2L V8 engines, Continuously Variable Valve Timing (VVT) adjusts airflow in and out of the combustion chamber under all engine speeds, which makes for better fuel economy and lower emissions. On the 5.3L V8 engine, Active Fuel ManagementTM deactivates fuel delivery to\
