Why does this happen on forums, where posters with a new account make their very first post replying to something from 14 years ago. Other times you'll see a sleeper-cell account quite a few years old come out of nowhere and post 1 thing all of a sudden. We have too many robots on the internet.

Edited to include poster’s name, I’m responding to:

Maybe someone just happened to be searching about a particular problem....it’s how I found this forum. And I too, have rough idle on my 2015 F150 King Ranch. Just replaced the throttle body. BUT, i unfortunately have to idle for a long time, in hot temps (to do computer work) in between ranch and HORSE work. So...I’m sure that contributes to the issue. Lots of idle hours and also lots of ranch dust. 😏
