I've got a 2009 F150 with the 5.4 an around 91k.
In the last couple months, I have noticed a rough idle sometimes but only in drive. It only happens when I'm off the gas completely and stopped I drive. It is most noticeable in drive throughout and at stop lights. It coincides with an RPM drop as well. No check engine light.
Anyone have experience with a similar problem?
Thoughts? Coil packs? MAF?
