searched all over the forum and concluded the phasers on my 2004 5.4 are toast. The truck is quiet at cold idle. However once it warms up, it is making all kinds of noise! Drive through ATM's and fast food windows are obnoxious. Noise goes away if I hold the accelerator and bump up the rpms over 1,100 or so.
So I tried to sort out which side the noise is coming from and i've pretty much decided that its both sides since it seems to be coming from all over! I can hear it in both wheels wells. I have one new phaser already so will start with the drivers side since that seems to be the easiest to do.
I read somewhere that you can ground out the VCT sensor, if the noise goes away, this confirms the bad phaser. How exactly do you ground the VCT sensor to test?
