I just posted another thread but wanted to keep the issues separate.
In my 2014 Expedition EL with the 5.4l, I’ve noticed for a while that there is a slight rough idle (like 1mm fluctuation on the tach but enough to feel it) when warmed up, but only when in P. If I shift to D, solid nothing.
No codes. Just scanned it.
Plugs are new. Coils still original at 105k miles.
Dealer maintained until about 3 years ago until I started to maintain myself following the maintenance schedule.
am I overthinking this and is this ‘rough’ idle little to no concern or should I start chasing a certain path?
Thank you all.
