Try cleaning your Mass Air Flow senser with cleaner from part store make sure it's for that senser n clean up throttle body real good with cleaner too. Also change out your PVC valve. I also had cooling fans not coming on as needed replaced couple relays n all is good now. Also check temperature control senser. Had same problems. Truck runs so much better now.

Rough idling at times, acts as if it’s going to die backing up at times, just changes the cam shaft position sensor, getting 10.4 miles to a gallon, no code other than it saying check fuel fill inlet,

Change out the VVT solenoids. To do this you, need to take the valve covers off but well worth it to get it running right. I bought mine off of Amazon. Make sure to order the Dorman ones...usually run bout $35 a piece on there.

Good afernoon, I own a Ford 150 fx4 2007 and recently I've changed both VCT (Variable Camshaft Timing), pinions and roller chains, a camshaft, spark plugs and coils. I have as well changed the oil but the engine is now giving off a sound at low revs, as if those chains were touching themselves.Even more, if I drive in reverse, the car usually starts trembling and, in order to stop it, I need to desaccelerate or stop it. No failure is provided by the computer, any ideas?

The problem you are talking about corresponds to some chain failure.
