Alright guys so I have a 2005 5.4L that is throwing P2270, P0022, and P0345. Gonna start at replacing that oxygen sensor, but think it's the cam phaser needing to be replaced?
Could also replace the cam sensors and vct solenoids, but what do you guys think?

Is it just codes or is it sounding different when you drive. If it sounds like it's dieseling but the sound goes away at higher speeds then it probably is your cam phasers. If it's not making a sound then could be cam sensors.
