I was driving my 2018 Expedition(61,000 miles) back from Georgia to northern Ohio when the check engine light came on. I kept driving to the next sizable town in Kentucky when the light started to flash and the engine misfired and decelerated. (I am completely non-mechanical so pardon my descriptions). The dealer there was very helpful, but I was anxious to get home last night. I made it with no further issues (except the check engine light came back on steady about 100 miles from home but with no misfires). My local dealership today told me the repair had something to do with the VCT and solenoids and something about a cam phaser. The estimate is just over $2,900. Has anyone else had issues with this and does this sound like the correct diagnosis?
