Default Can I Disable AFM?

Since the major engine work I've recently endured, I've been wondering about disabling the Active Fuel Management system - a VERY popular action by 08-09 5.3, 6.0, 6.2L owners. Anyone know if this would affect the hybrid system?

Obviously mine was not a bad injector. It was another stuck lifter. I spent another $1600 to replace the cam shaft and all the lifters again.

I'm afraid if you have a stuck lifter, you may have worn cam lobes. And there is also a plastic tray that the lifters sit in that tends to crack, causing the lifters to spin around and get stuck.

How did yours turn out?

There is a 5-Way plug way in the back of the engine not too far from oil pressure sender. If you un-plug it. No AFM. There will be codes and a CEL.


If Auto-Stop is disabled, it affected the Hybrid.

What about using the RANGE TECH. after deleting VLOM and new ls7 lifters? Will it throw codes?
