2007 GMC Sierra with active fuel management?

Question

I like the active fuel management except for one thing.It's too touchy.The slightest thing puts it back to v8 mode.So does anyone know how i could add a switch to prevent that?I'd like to be able to force it to stay in v4 mode.Does anyone have any ideas how i could do that?Does it work off the TPS?If not what triggers it between modes?Thanks in advance.

Answer 1

I agree with the other answer. Its a new technology and it will take a few years to really become "normal"...until then just persist because any fiddling will void your new car warranty.

Answer 2

Don't mess with it. You will void the warranty and could really mess something up. Talk to your dealer in see if this is normal.
