If you do not understand it, or you need more information from me, or need me to go in more detail. Do not rate yet, just reply.

Also understand fixing cars often requires sophisticated tools, that you may not own. So even if you can not do what is outlined in my answer, that does not mean my answer is wrong deserving to be rated negative.

No recent work, I replaced the camshaft position sensors, but it's still misfiring on idle and the error code returns after reseting it.
No accidents.

ok how many miles on the vehicle ? how long did you own the vehicle? at what interval did you change the oil?
Customer: replied 1 year ago.
160k miles owned it for 12 years, changed oil every 10k with synthetic oil. Does all that really matter?
Expert:  Wolfgang replied 1 year ago.
it is recommended every 5k miles for oil changes per the factory . what has mostly happpened is the variable timing solenoids has debris from a screen that is part of the timing case has broken off and causing your timing issue . it cannot adjust so then the timing off is at the cams. it is an expensive repair . the timing case assy and the gears of the camshft needs to be replaced. the timing is oil pressure controlled by the electric solenoids regulating pressure. so the solenoid mechanically is hanging open and causing this issue!! in parts alone is about $3500.00 + labor of 20 hrs
