2005 Lincoln Navigator 5.4L 3V P0012

I have just done the whole timing with new chains, oil pump, tensioner, and new cam phasers. The truck starts up fine and idles fine but when I took it for a test drive on the highway when I come to a red light it starts to misfire and stall but when I rev it and when the RPMs go back idle it is fine no misfire no shaking. The only code that popup was p0012 “A” Camshaft Position – Over-Retarded Bank one. I also change the Camshaft sensors and the VTC solenoids.

 

Please don’t double post, thanks.

Those are notorious for having problem with the cam phasers that's probably the problem they just break down it's not the actuators but the actual cam phasers themselves
