Help needed!!!Ignition timing retard problem
I now have 2 5.4 f150s that pull ignition timing for no apparent reason. No codes at all. But if you unplug knock and cam sensors it runs mint and timing works correctly. Both trucks do have the phasers locked out and levinis program installed. They have been looked at several times by mechanic and dealership with no explanation.
