Cam phasers?
2005 F150 5.4L
160k miles
Runs ok at startup (closed loop?) may occasionally misfire until warm (mainly P0304 and/or P0308)
After warm throws different combinations of P0171, P2198, P0022, P0174, P304, P0305, P0300, P0021 with rough idle.
Then low power when driving
Am really leaning towards VTC system.
Should I replace phasers, chain, tensioners, guides... or should I keep simple and shoot for solenoids .... or all of the above?
