Been a long time since I posted anything on here, been super busy with other cars and work.

But, I recently decided to change out my cam phasers(old ones lost all tension.) Truck ran great before and really didn't make much noise, but I would occasionally get a slight missfire but overall ran well. Took a few weeks to complete as I've had other projects that took precedence over this truck.

Once I finally got the truck back together it ran terribly, barely idles and has absolutely no power. The only code I get is p0354. Unplugging either cam position sensor makes the truck run much better. I've put in new cps, new vct solenoids, changed oil, battery and everything I could think of. Truck makes good oil pressure, and proper voltage.

Any ideas would be greatly appreciated.

 

cam phasers don't really lose tension, the seals in the tensioners blowout and they can bleed oil pressure creating timing chain slack and/or broken chain guides. I just went through this exact thing this past summer and ended up putting a complete timing kit in.

Did you pull the front timing cover off and change anything else under there? If it was just the phaser that you changed out, I'm wondering if the timing is off by one tooth.
