My truck was doing the same. The last time is occured was april 2nd hasnt done it since ... the only things ive done dofferent is that i started using royal purple oil and Wix XP pil filters instead of motorcraft. A little more expensive but a higher quality oil... and i also replaced my battery as it was starting to show signs of dieing.

Im not saying to do those things as mentioned above but im going to continue using RP oil and see how much longer i can go without the problem coming back.... my truck is currently at 160k miles.

We offer a complete, permanent solution for the 4.6 and 5.4 3 Valve modular engine's cam phaser issues. Our cam phaser noise repair kit will eliminate the moving portion of the cam phasers that is lacking lubrication by locking them in place, this quietens them up significantly. Of course we always recommend to make sure there are not any other issues like a broken timing chain guide or something similar while doing this installation.

Other than the usual culprits, these engines are very durable and have been proven to live a long trouble free lifespan.

We have customers telling us every day that they wish they would have found our solution sooner. You could replace all of the timing components but that won't help with the phasers not getting the oil pressure and lubrication they need.

If we can help with anything or if you have any questions about the kit please don't hesitate to reach out to us.

Could be plugs or COP, or combo of both. Most times these song throw codes but are annoying as heck. Worth a check anyhow I'd think.

Have had similar issues. 2004 F150 Lariat, 5.4, 170K miles

3 months ago engine light. Rough idle, some knocking. Code P0022, Suggest replace Cam Sensor (Bank 2) Drivers side. Done engine light off and running fine.

3 weeks ago, engine light. rough idle, no knocking. Codes P0022 - Intake Position Timing - Over Retarded (Bank 2), Code P0171 System Too Lean (Bank 1).

Suggest replace VCT Sensor Bank 2. Did that and cleaned MAF Sensor with Appropriate Spray. Still a rough idle, not horrible, but rough.

Faulty Part? Removed just replaced VCT and put in a new replacement VCT. Engine light again. Still rough idle and pulls the same codes P0022 and P0171.

Any suggestions on next steps?

Thanks in advance for your help!

Wrong tread.

Mine did the same 2 yrs ago, I threw in 2 new phasers, 2 new chain tensioners, new chains and guides.

Turns out it was one my tensioners leaking oil which caused my phasers to fail.

Good luck...took me 7 hrs to swap it all.

I’ve had the exact same problem. Common on this engine when it has not been properly maintained. Easy test, pull the plugs on the cam phasers. Drive it, it won’t have the power but will still go highway speeds. If that quiets the engine you know that is the problem. BG makes a kit to flush the tarnish and I have changed the oil several times. Pennzoil Platinum full synthetic 5w 30 was highly recommended because it has lots of detergents in it that will clean out the crank case as it is regularly changed. It’s also good to use a motorcraft filter as it is engineered differently from an aftermarket. Haven’t had an issue since.

Hello I would like to to get a quote on the cam phaser issue

I have a 08 5.4 170k I retimed the engine bought it non running it starts right up and runs fantastic until the engine reaches exactly 190 degrees then it idles rough no matter how you treat it it will be nice and smooth idling all the way up to 189.9 but the first time you touch the throttle at all over 190 it idle rough until it cools down still runs well and lots of power but idles really rough like everyone else I have a code saying cam and saying advancing/retarding full timing kit with phasers and vvts it does have a very weak battery from sitting. And its now been at the dealer for diagnoses for well over a month they don't know anything yet I tried unplugged the vvts before the problem and it still had the problem my only leads asking everywhere I can think of is oil pressure but if its oil pressure why can it idle perfect for literaly hours as long as you don't touch the throttle at all it runs really rough and shakes often a light ticking knock kinda noise but usually pretty quite just sound like a engine about to stall
