motor running rough

[josephmast94]

My 05 expedition had started running a little rough, mainly just when taking off it will bog down. It is showing 4 faults:
P 0011 camshaft position actuator A bank 1 timing over advanced
P0340 camshaft position sensor A bank 1 circuit malfunctiong
P0344 camshaft position sensor A bank 1 CKT intetmittent
P0420 catalyst below threshold bank 1

Can anyone help me out?

Most of those codes say there's something wrong with the camshaft sensor on bank 1, this may be the sensor itself or the wiring to it. You can try to swap the two sensors and see if the codes follows the sensor.

For the P0420, you may be looking at replacing your catalytic converter on bank 1, or if you're lucky, it's just the downstream O2 sensor..
