2012 FX4 - Steady Pedal in Park - Intake is pulsating
All, I have a 2012 FX4 3.5 Ecoboost that has a S&B Cold Air Intake. I was holding it at a steady 2000 rpm in park and the intake is pulsating. Increased suction for 3-5 seconds and then releases.... I hooked up to monitor it and see what was happening but I didn't see anything in the parameters I am monitoring that matched that oscillation cycle.
I have been suspecting my phasers are going out. 183k miles. So I have been monitoring the cam errors. They are adjusting or showing all to have error approximately every 38 seconds.
Log attached. Snapshots of cam movement occurring. I'll try to take a video of the sound the intake is making.
Any help in pointing me in the right direction is appreciated.
