[s-cars] dangerous binding/sticking throttle issue?

[JC]

I posted this on QW but think it might be a better question for the
eggzperts over here... any suggestions hugely appreciated as always..... 
 
Always wondered if I had a stuck throttle if I'd have the presence of mind
and reaction time to shut down the key fast enough. Apparently I do. 

Happened on first WOT pull after a whole bunch of work including oil change,
installing Samco's and metal intercooler etc. etc. 

Pulling over couldn't find a single thing sticky w/ the throttle cable or
shaft/plate motion. Started up fine, another drive and no repeat, BUT I
occasionally seem to feel some mechanical resistance/stickyness/binding down
just off idle... like shifting when I first start to press there's a bit of
binding then it releases. Maddeningly whenever I check this static w out
engine running I can find NO problem and everyting runs smooth as silk. 

Is there any known problem/issue/thing-to-check here? Cruise linkage seems
fine and never touched. The dashpot thing I removed briefly to make getting
the hose clamp on easier but AFAICT is all back exactly as previous and
working fine...
