[V8] Stuck Accel?

[info at speakoutpro.com]

OK, this goes back to the SADA days (Sudden AUDI Death by Acceleration).

My 1990 V8, from time to time, sees the accelerator pedal not return to its
normal quiescent state and gets stuck with RPMs higher than they should be.
I revolt by giving the accel pedal a quick stomp and it returns to normal.
Is there some place in the chain of cables, linkages, bearings, etc. that I
can spray anti-SADA (WD-40) and be done with it for a year or two?

Or should I do nothing and call 60 Minutes?
