Re: 09 5.4 VCT actuators cycling on/off at idle?
Posted to Technical Discussion Forum on 2/11/2018

Thanks Kevin!

So I guess the pcm doesn't like the aftermarket actuators, sets cmp, ckp sync codes and then the pcm goes into some kind of limp in mode, where it continues to cycle the VCT actuators on/off, even at idle!

Very interesting!
