The older, original cable (on my 95) had about 4 to 5 inches of exposed twisted strand cable near the end. The snap on ball type connector (to the throttle linkage itself) was pressed to this wire cable. This was prone to fraying. Mine was almost to the point of breaking when I replaced it myself. About a year later (~ 2 years ago), a dealer replaced that cable with one that had no exposed wire, saying it was the new updated version. This one is sheathed in plastic all the way to the ball type connector. Other than the cable, not sure what else in the linkage DC plans to check and replace. May just have a dealer look at it before scheduling anything.
Regarding stuck throttle pedal, a frayed throttle cable could cause the symptom described, as also could corrosion and dirt built up in the linkage itself. There is a throttle return/tensioning spring which sits under the P7100 to the rear, which if broken, would make your truck almost undrivable. Happened to me about 20 miles from home and barely made it back. Carry a spare now.
Regarding the number of recalls, owned a 92 Explorer that had a bunch.
