Stumped with 2010 250 5.4 4 valve
Over a 2 month period codes for injectors, coil packs, cam sensor, EGR valve, finally someone that told me timing chain jumped. Put in new phasers, chains, gears , tensioners, runs fine when cold but as soon as warm only idles on one bank, code says cam shaft 7 degress off.
Many people trying to figure this out but no answers yet.

I know you don't want to hear this, but you may have to open up the parts for bank 2 cam components. Bank 2 is the bank on the driver's side.
Before starting to recheck your work, make sure the oil control solenoid for that bank has good connections and remove it to check for foreign matter clogging the passages and screens..After checking that if you want to, you can switch the solenoid with the other bank to rule out a solenoid valve problem . If malfunctioning due to component failure the code will switch to the other bank. Make sure all connections are good and secure to cam sensor and oil control valve.The misfire on cyl #3 could be the result of a phaser problem OR a clue to look for something unusual in the #3 cyl area.Something is not right with the cam components for bank 2.that is affected by engine temp.
